Yamaha F300 or F350?

We just installed a new yammie F250 on a 23 with no bracket.

Optimal cruise is around 4200 RPM @ 30 - 32 mph getting 3.1 mpg. WOT is 45 - 47 depending on load. Planes easily with very little bow rise.

Food for thought............

personally, I would love to see what a 23 could do with the 350, but the f300 may be a better choice because of the lighter weight, probably cant go wrong with either.

I would go with a f300, I ran a 26 JB with 350 and really did not like it. Fuel burn was high at cruise, a Seacraft will do much better with the new light yammi 4s. Call Don and get his take, f3oo and full hermco would be nice..

Snook, you can search my build thread in march of 2009. I posted pics of the whole project. I love the bracket and performance on the 18'. I like the closed transom. The real shame is that i haven't run the 18' since i bought the 23'. I'll probably put her up for sale since I now have have two kids and the extra room on the 23' is nice.
