Two questions

[Black Panther 1,776]

1) for the mechanics.  I have replacement 4hp 4 stroke yamaha.  The old one always started on the second pull. This one on the 7th. Do I have to live with this.

 

2) my favorite chart plotter app (mx mariner) is no more. What would you replace it with. Preferably free. Preferably able to download nz charts, free. And easy to use.

1.  Not normal.  Return to sender.

2. Open plotter.  Runs NZ charts just fine in vector or old style raster format.

They lost me with the first paragraph

Bought the outboard for peanuts on trade me.

Yeah sorry, open CPN is the plotter.  Has versions to run on android phone or tablet, windows, Linux, and apple.

Orca navigation app is simple and super easy to use. The charts look great. Syncs with all the devices you load it on. You can use it free in cell or WiFi range. For maps offshore and away from city verge there is a annual subscription. Bit worth it in my opinion. They sell some add on hardware which has some really useful features and makes the system very accurate with it's heading sensor. Works fine without.

Do you have / did you buy the Orca specific tablet they sell?  The big selling point is 1200 nits, so sunlight readable on the most sunny day .....

If your old one started 2nd pull, why did you replace it?

and what did you do with it? (want to sell it?)

In theory these little outboards are super easy to service. It could be something as simple as a gummy float in the carb. Where petrol has sat in it too long and gum / resins from the petrol have fouled parts of the carb related to supplying fuel. Especially with all this 'save the planet, stop climate change bio-fuel' in it, which adsorbs water and goes stale like a bastard. A gummy float can mean either the carb floods on starting, or the bowl drains so when you go to start it you have to fill the bowl before it starts. 7 pulls sounds like that. Short story is hard to start is often a gummy float.

If it isn't a brand new unit under warranty, as in a cheapy off TM, I'd pull the carb apart, spray large quantities of Carb-cleaner (CRC product, smells lovely / sweet), and put it all back together. Take photos as you pull it apart, so you can put it back together the same way. Or just watch some U-tube videos, they seem to have videos on how to strip down and fix almost everything these days. I would say you don't need to be mechanically inclined to strip and clean a carb. Just organised enough to not drop the little screw overboard, and intelligent enough to put it back together the way you took it apart, and not break anything by trying to take it apart if it doesn't come apart by un-screwing.

If it is something to do with a carb mixture setting or idle screw etc that is a tad more complex. I either wouldn't touch it, would refer to U-tube videos, or if it is really causing you a problem take it to a professional and part with modern currency.

If my 2hp gets temperamental this is what I do (strip the carb), then it starts second pull every time.

Change the plug as well as cleaning the carb, or at least clean it and check the gap.

Thanks, I'll check it out.

I just use it on my pixel 7 or Samsung activ tab3.  As long as they are close to me either are bright enough.
