Jeez, dude you have all the fun.

No kidding . I can't think of why someone would do that to a stock 454mpi set up on a V hull.

Well it looks like you are finding your problems at least. You should be running good this summer when you get it taken care of! Good luck.

You've done a great job getting it figured out.

Wow, I thought I had my hands full.....can't wait to see what you get outta her now!

I feel my next boat will be an Islander, as I love the open bow also!!

Thanks for the encouragement.

I guess that sometimes people change the gears for high altitude. This certainly helps explain the high slip numbers, lol. From what I figure the 25p 1.65r is pretty close to the 23p 1.5r. Bummer that I sold my 25p now that I'm getting the motor sorted out, lol.

Well now you can salvage your sanity!!

Trees are greening up ice has thawed lets see how this boat does this summer

High hopes! Lol.

I have to pull the motor to change out the coupler, and hopefully have time in the next week or two to do so.

Just glanced at the first few pages of the thread your turning the RPM to run mid 60's with a 23p, so I wouldnt say its an engine issue.... there is NO WAY you have a 1.50 to 1 gear set.... my 252 islander with 310 hp runs 54 with a 21p.
