I have 1986 268 Sundancer with a single 350, and it is underpowered. If
you have 2 engines, I suspect planing not to be an issue, but I did not
think the 1988 268 came with 2.

I switched to a stainless prop that helped the most and added outdrive fins
too, but still is a challenge to get it on plane (without running it to the
limit). At 3400 rpm the 4 barrels are open and gas consumption is double.
If you do only have a single and want more info, let me know and I will give
you more facts.

We do love our boat (YesDear) and plan to keep for a while yet (going on 10
years now).

I require 3400 rpm to maintain a plane and that results in a 20mph cruising
speed.

I'm looking at buying a 1988 Searay 268. Can anyone tell me if the 5.7
(350)
liter engine is enough power or should I make sure to get the 7.4 (454).
I'm
wondering if cruising in the low twenties mph what kind of rpm the two
engines would be running or better yet gal./hr. Any facts and opinions are
greatly appreciated.
