I would think the weight would be close I think the old owner told me about 4400 ready to run. I think Fountain has a better record for stability for these size boats plus if you have K planes already 90s could be attainable. Talk to Brett at bblades & I'm sure he can get you real close with a prop + they have a loaner program. I would own the maximus props he loaned me for havasu but the river flooded right after we got back & my house was a victim, hense irons in the fire. Randy

There are a few different fuel rails depending on the year of your engine. As long as you do it right the first time, you will have a very reliable piece making 625-650 hp. The little blower will really wake that engine up.

Its not properly tuned and you may have a fuel supply issue, where are you located? I can almost guarantee your iac isnt properly zeroed down to 20 counts or less warm, this means cold its wide open and still not enough and warm its probably still far open. Your tune prob needs more initial timing and possibly pw programmed in and spark stabilization may need to be widened, Smitty
