   Not sure about as late as 1988, maybe, but I know a few earlier 2001's came with factory 454s.  Since you need a new engine and have 454s laying around, go for it.  But I wouldnt swap a 351 for a stock 454 just to get great improvements in performance without having some other incentive, like you do.  The 454 2001 I am familiar with was good for 50.xx  mph.  Not a whole lot more than the stock 351.    If you are going to spruce up your 454, go for it.  There is a BFN on the site with a spruced up 454 that was good for mid 60s.  Doubt you would get close to that in the 2001 hull, plus that was a very spruced up 454.  I'll let the guys who spruce up engines pick up from here.....

	Hello everyone! What 454 Parts work best for speed? Has anyone put a 454 in a 1988 Ski Nautique? Now, I already know what you're gonna say; "Barefoot", RIGHT?!! Nope, completely different V-bottom Hull Barefoot Nautique is V-Bottom. Ski Nautique is Semi Flat Bottom (Smaller wake) I assume given the same engine, faster? Barefoot Nautique is basically a 454 Boat. And a Ski Nautique Most likely was NOT ordered with a 454, Right? So, I suppose a 454 and a 1:1 Velvet Drive will just drop right in, Right?!! AND What 454 Parts work best for speed? Work in progress; A nice 1988 Ski Nautique Cracked Block or freeze damaged low performance 351. Parts: I do have a few 1980 2 Lefts and 1 Right Hand Mercruiser 454s laying around, another 1 pair of Peanut port Heads, 1 pair of Oval Port Heads, the 3 engines already have Oval Port Heads on em and a pair of Left and Right 1.91:1 Borgwarners which I know Can't use for this build. Also, I have some experience with 4 Round Peanut Port Truck Heads with 2 Mecruiser Magnum Cam 454s turning 4000 (My exact Target) rpm, in a 10,000 pound 1980 Searay 31 Foot 11'11" Beam Express, Straight shafts, turning 1.88 to 1 Borgwarners and 17-18 3 blade Props for 37 MPH on the GPS in flat water (Add 3 mph for a good Head wind and 2 foot chop water) and I except, the engine Parts are a good guess, the Searay is going faster than it ever Has and as fast as it will ever go for low budget Engines. However, Is this the answer for a light 1988 Ski Nautique? Thank you for reading! New Dude
