Outboard Discussions

. . . I would like to try the Yamaha 6hp 4 stroke.. but I doubt it would fit in an Ariel well . . . Also, if anyone has successfully mounted a Yamaha 6/8 4 stroke in an A/C well I would like to know of it.

:

As noted elsewhere in this thread, Tohatsu makes the Yamaha and Nissen 4 & 6 hp 4 stroke engines Going to an 8 hp 4 stroke requires major modification to the engine well in the lazarette. See Ebb's photo gallery thread for one such modification

Tohatsu does make Nissan and small block Mercury outboards but Yamaha is made by Yamaha.

FWIW,

The Tohatsu plant makes the Mercury, Nissan, and Tohatsu outboards. They are the EXACT same motors, right down to the paint. The Mercury dealers will try to convince you otherwise but there is no difference. (Other then the Mercury being much more $$$)

I have found the zinc Yamaha sacrificial anode will last a couple years in fresh water, less than that in salt water. In fresh water a magnesium anode should be used but Yamaha doesn't make them unfortunatelyso I have to be certain to keep the lower unide and propellor painted so the aluminum doesn't become the sacrificial anode. I only use TriOx bottom paint as it doesn't react with the aluminum andis slime/algae resistant.

May I ask you OB motor guys this:
Can (a Yamaha 8/4 stroke in my case) an outboard be fresh water flushed while in the raised (tilted) position?

Thanks.

Ebb:

Does your engine have a flushing port for a garden hose attachment? ie flush port at the top of the engine block. If so then you could flush it in any position because you don't have to run it during the flush. If on the other hand you are relying on rabbit ears (flushing from the bottom of the lower unit) then I would not flush in a tilted position because to get full effect of the flush you need to run the engine. I would worry about the problems with the oil sump/pump getting starved if not run in a vertical manner.
