    Personally I'd be hesitant to nearly double the weight hanging out the back on that bracket. I'm pretty sure I remember it being an 8 that was on there prior, so the 9.8 was already an increase. IIRC this was done about 10-12 years ago, so motor isn't a spring chicken but also isn't as old as many...

    Few things to consider:

    A) what can the bracket handle? not just a concern in terms of raw weight sitting on the bracket at rest in the marina, but as the boat bounces up and down in chop, inertia will mean theres more than 40kg of force being put on the bracket and its mounts.

    b) lifting on and off. Although not a huge deal if not doing it often.

    C) in general adding weight to the ends of a boat is bad for performance. It increases pitching. Plus when it's out on a bracket/lever an extra chunk out the back, the effect is magnified. 830s are light boats and quite weight sensitive - you'd want to be sure it's not going to make the boat behave badly when you try to sail upwind in a chop.

     

     

    Yes the same concerns I have.

    I'd love to go the lighter weight of the 2 stroke, but the low running noise, lack of smell and fuel economy (in terms of range, not cost) are very appealing.

     

     

    Ratings for Rise & Fall brackets (for both 2 and 4 stroke motors) – standard shaft, up to 25hp (18kw), long shaft up to 20hp.

    Maximum motor weight of 58kg.

     

    So 10 Hp and 39 kg's would seem to be well within, decisions/decisions!

    Years ago I sailed on revolution blues (830). It had a tohatsu 9.8 2 stroke on it which seemed to perform well and I remember  a conversation at the time about how it was the lightest of the 9.9ish hp motors.

    Nice, this is revolution blues we're talking about :)

    Age of the motor a good part of my reasoning, funny to think its the exact same motor you used and discussed all those years ago!

  3. Just realised both your boats are slightly shorter, was having a senior moment and forgot ours is an 830. So the power output of the 6hp is probably a real concern in weather.

    So now im looking at the Tohatsu 9.8 4 stroke. Just heading up tonight to check what bracket we have, if it's a real tenob they are rated to 20 hp long shaft and 50 kg's.

    Switched from a 8hp 2 stroke Yamaha with high thrust prop to a new tohatsu 6hp 4 stroke sail pro (ultra long shaft) on our Ross 780. Outboard mounted on bracket out back. Love the tohatsu would never go back to 2 stroke. SP model comes standard with yacht specific prop, charging system and ultra long shaft. 

    Thats great to hear....Are you in the Hauraki Gulf, have you had it out in any adverse weather?

     

    I'm really keen on the 6hp 4 stroke after yours and Flaming lips experience but the 3 HP difference worries me for wind on the nose, swell/chop conditions....???

     

    per this kind of comment...

    I've happily used a long shaft, 6hp, four stroke in the past which gets the boat along nicely when there's no wind, but we need to consider what happens when we're pushing into rough conditions and there's an issue with the rigging which means sailing is not an option (which happened to us last year) and motoring out of trouble is the only choice left.

    Just put a 6hp 4 stoke Yamaha on Flaming Lips, only used a few times so far but pushed her along nicely at 6kt in flat water with a very dirty bottom or 4+ into 15 knots of breeze. very clean and  quite, comes in at 26kg. 

    Interesting alternative, quiter, no oil to premix and that is slightly lighter. My only concern would be in swell. Does it reach as deep as the old motor?

    In larger or shorter harbour type swell or chop we will have the motor out of the water on occasion.

    Why are you replacing it?

    26kg vs 39kg is a big difference for lifting on and off the back, imo. 

    Its semi permanently mounted. Removed annually for new waterpump and service.

    Repalcment is age related. Just for safety and reliability, plus the cover is held on by a ratchet strap as the rubber seal is apparently unavailable, looks tatty.

    For the safety of the family, and the by the time we sell the old one, the cost isn't massive.

    I had a scare last season, turned out to be spark plug related and easily fixed but it REALLY put the shits right up me being stranded out in the gulf with wife and 7 year old daughter on board.

  7. Looking for advice on replacing our old, working pefectly 9hp Tohatsu 2 stroke.

    Tohatsu seem well priced and it likely ensures our fuel line and charging lead will fit but open to suggestions on alternative brands if there is any benefit.

    Mostly, i'd like to know if there is any benefit to going to a 4 stroke engine other than not worrying about premix.

    Im attracted to 4 stroke for less noise and smell BUT am worried the weight difference on the outboard bracket might be a bit much, though I can likely beef up the boat side mounting. Current engine weighs approx 26 kg and the 4 stroke equivalent is 39kg's.

    I presume a 4 stroke has better torque which might be an advantage?

    Giday Rg... firstly I am solo sailing, so can't rely on a crew to share overnight watches etc
    I would say my experience is 'low to medium'...i.e I have not been up and down the coast 20 years in a row like some of you on here...a handful of times - yes

    I want to head for Barrier (Port Fitzroy area) and then to Bay of Islands with a couple stops....from tomorrow I have to work for three days, then Im off for a month...the SWs' run out Friday evening and from Saturday all the wind models are showing building easterlies for days and days and days....my boat points "ok" for a 26 footer, but as I understand it, the easterlies will bring a big sloppy swell...I guess I could just suck it up and forgo Barrier and maybe do that on way home and take the easterlies on the beam, big sloppy swell and all...

    Of course, and easterly makes the whole of the coast from Whangaparoa (where I am based) a lee shore, and while I don't think conditions will be dangerous, as I'm solo I just need to make sure I have a sound plan and don't do more than one overnighter in a row....

    Any tips appreciated,

    Cheers 

    I dont have any toips for you. My tips would likely just be poor advice :)

    Congrats on even planning such a big journey. I hope you give us updates as to how you go and wish you all the best.

     

    My planned journey is from Gulf harbour to Kawau with a (sailing) sensitive wife and 7 year old daughter. Friday looks ideal at 13 knts SW, the return Monday /Tuesday at 20 knts NE predicted, not so much. I think we'll be fine if it doesn't go any higher than that.... fingers crossed.

    Easterlies for Africa for number of days from New Years eve....completely spun out my plans ....probably have to make my way to the Eastern Gulf and just work my way up and try make use of the Easterlies as best I can rather than fight them...the wind doesn't care about my or your grand sailing plans for the new year holidays -- ah well... such is life

    Where were you headed and from where?

    Just trying to figure out what the E prevents you from doing and if it shoudl prevent me from doing it! :) (who knows far less of directions, sailing directions etc.)

  10. I think I have wrapped my head around the backstay. Roughly speaking tighten for upwind, loosen for downwind.

    But what purpose do the side (aft each corner) backstays do?

    Presumably they act more for the headsail shape than the mainsail?

    - Overall Im trying to learn how to sail our boat more effectively. She always seems so overpowered, not so much through the tiller but in lean angle. Im told to sail Ross 830's as flat as possible.

    The sail shape is (to me) always quite full, I suspect this might be down to age.

    Normally I would increase the outhaul tension but this seems to be already max and still too full.

    Serious question, what do you guys use it for?

    The boat? Sailing around  the gulf. 1 day or 2-4 day trips at the most. So far anyway.

    The Radio? Weather, reporting trips.... Mayday if required :)

    Having a 7 year old daughter on board, im a bit more conscious of these things nowadays. Though I was pretty on to it in previous boats. Being trailer sailers back then, I was pretty cautious then as well.

    You shouldn't need to hold the international button while transmitting. That means that you have to use both hands for the radio. All radios should be able to be SET to either US or International.

    Please don't go the handheld way, the height of the aerial for VHF - line of sight- is critical.

    I would keep your new radio, the technology has been changing quite a bit over the last few years.

    For some reason, maybe turning the main battery switch off (? ..or maybe im just presssing the buttons by accident...)) the radio defaults to not INTL. Switching it to INTL leaves it there until...I don't know what or why yet. Still working through that.

    Yeah, the new one woudl fit better as well....Still a work in progress.

    Appreciate the advice :)

    Yeah you could use it on a conventional set up - just use the middle hole and adjust the jib cars as per normal. You’ll need to be careful with it flapping during tacks though. That chunk of aluminium could hurt stuff. 
    and yes we’ll be up on Boxing Day to head out for a cruise. 

    Yeah that Aluminium is a big heavy peice to be clunking around.

    Presumably a sail maker could remove that and make it a standard style?

  14. SO.......murphies law.

    Apparently you have to hold down the INTL button rather than just press it.

    Now our old Apelco radio works fine, with the old aerial!!!

    Agggghhhhh. Hoep Burnsco will accept the return.

    But it turns out our approx 2 yr old Deep Cycle Battery might be dying!

    Boats!

    Hopefully a nice slow charge over the next few days is the solution.

    Take the new radio back to Burnsco and swap for a handheld VHF.  They just work!

     

    Yes, that was a consideration.

    I did wonder about the range with such a short, close to sea level antenna though.

  16. FYI- I have just bought the GME GX700 from Burnsco as the new antenna didn't work.

    I have tried pressing the INTERNATIONAL button and unless im doing it wrong still not working. Though I suspect it is related.

    I figure its just not worth the hassle (im running out of time...weather depending) so gave in today and got the radio :)

     

    Appreciate all the advice and suggestions.

    Yep- they will, but callsigns have nothing to do with VHF licences. So- you can  have a callsign, which is a good idea anyway, as it a] identifies your boat [as  130 plus boats on the gulf are called "kingfisher",]  and b] if you don't have a callsign, they will give you a temporary one to identify your vessel until you do.

    Coastguard are not interested in any enforcement, they are only concerned about your safety. So feel free to call coastguard radio, set up a trip report [ or use the free coastguard app ] and be safer. Coastguard do not report people for not  having a licence etc.

    eg as I have clearly heard several times over the radio. ---"coastguard radio - this is [ for example] bluebird". Response - " bluebird- do you have a callsign. NO, no callsign. "Bluebird, until you get your own callsign, we will allocate you a temporary one,. Where do you normally launch [ etc] "bayswater- your temp callsign is "Bluebrid - Bayswater, go ahead with your trip report.

    easy. Doesn't have to be an emergency.

    Appreciate the advide thank you, presumably ch 16 isn't ideal for this kind of chat. From Gulf Harbour and north to Kawau region, what is the best channel to use?

  18. 3 hours ago, SeaAir said:

    Hi... try channels 19..20 or 21 depending on which part of the gulf you're in.   Good luck...  

    Yeah, I tried that last night with nothing. Might have to commit to new radio.

    Thank you.

    The jib clew is for attaching to the self tracker track (which doesn’t appear to be on the boat anymore). The curve with different holes allows is where it would chuckle to the sheet on the self tracker and dependant on which hole you chose gives you different trim for the jib - same as moving you jib cars forward or aft on a conventional set up. 

    Found the quote :)

     

    Mint thank you.

    Aha, Okay, so do you think we can we still use this sail or is it a bit hopeless without the track geometry?

    Are you guys sailing your lovely boat this Christmas?

     

     

  20. I can;t seem to be able to quote (or edit for thatmatter)

     

    Y88 5241

    Fantastic thank you!!

    We were told the boat had a bow sprit but I thought we got ripped off :)

    Now to figure out how to use.

    Much appreciated.
