Re: omc/speed
Dag, I have a 2.3 Cobra on an 18.5 aluminum Crestliner. I run anywhere from a 13.75x15 to 13x19 depending on what I want to do. The 17 is my favorite overall. With the 17 my top end is ~35 (w/speedo) @wot even with 4 people and full tank. It will pull tubers and slolom and still idle for putting around.
I've also thought about the 3.0L for a few more horse. But, my 2.3 runs so good and has enough power for what I need I just can't justify the cost.
