rossd 14 Posted May 7, 2019 Report Share Posted May 7, 2019 For the last little while only 1 blade has been coming out and have had to blip the throttle to get the other one out. But few days ago it wouldn’t come out even after a couple of rev sessions. In the end stuck it in reverse and then forward and all ok. I think the vibration did some damage to the shaft strut as leaking a bit now. The lesson as always is lack of proactive maintenance will always come back to bite you on the bum. Need another prop, geared folding 2 blade should do the trick. Yanmah 25mm shaft. Existing is 13.5x9 LH , handbook says 13x8.5 and previous paperwork mentions 14x8 so some wriggle room. Anyone got anything or know likely prospects? Thanks Quote Link to post Share on other sites
raz88 59 Posted May 7, 2019 Report Share Posted May 7, 2019 https://www.trademe.co.nz/2047246717 That looks like a possible? Quote Link to post Share on other sites
wheels 403 Posted May 7, 2019 Report Share Posted May 7, 2019 Why do you need a new one though. Surely a clean and lube should sort it.Also, unless you have a continuation of vibration even with the prop blades out, the shaft should be OK. If the gland is just a stuffing type, simply tighten up the gland a tad. Quote Link to post Share on other sites
waikiore 75 Posted May 7, 2019 Report Share Posted May 7, 2019 That is a saildrive prop Quote Link to post Share on other sites
rossd 14 Posted May 8, 2019 Author Report Share Posted May 8, 2019 Razz88. Sail drive quite different. A spline rather than taper. Wheels. The blades are as sloppy as. It would need a new pin, rebushed and machined blades etc. could be done but also times a problem as no facilities here other than putting down on the boat ramp between tides. I think the shaft, stern tube and gland are ok. It’s the oddball setup where the shafts off the centre line off the boat and has a seperate support strut , which is what took a beating.

rossd 14 Posted May 9, 2019 Author Report Share Posted May 9, 2019 3 blades would be cool. Unfortunately 380 or 15 inch will be to big I already have a clearance problem with rudder on full lock. Quote Link to post Share on other sites
rossd 14 Posted June 28, 2019 Author Report Share Posted June 28, 2019 Bit the bullet and got a new one. Surprised they said a geared one is no more efficient than floppy so floppy it is. What’s the E 19 mean? Also with prop speed it says sand 80 grit so does that mean sand of that nice polished surface?. Do you propspeed the shaft anode? Quote Link to post Share on other sites
Frank 28 Posted June 28, 2019 Report Share Posted June 28, 2019 That is a Bri Ski Prop and I thought they went out of business years ago ? I found the geared unit was better in reverse, its a Briski on my saildrive and it has given good service. Quote Link to post Share on other sites
