Re: Nissan / Tohatsu 6h 4 stroke
99% of everyone wouldn't even notice that it is underpowered. The only reason I did is that I bought it specifically to bump my power up a bit from the 4hp I had. It going from 6.1 knots or so down to 5.2 knots when I put this engine on the boat was a bit of a shock. After playing with it for 6 months and multiple props dropping the pitch each time I finally got it up to just a hair under equivalent performance of my old 4hp.
Interesting suggestions on the jets.. I have thought about it before but didn't really know enough about doing it myself to be more than dangerous. I don't doubt that the engine is capable of 6hp. Just wish it came from the factory that way, since that is what I paid for.. Significant premium on the 6hp over the same engine in 4 or 5 hp.
