22' Sea Skiff

Post by averagejoe » Sun Nov 19, 2006 9:12 pm

What cruise speed & top end improvement can I expect with a 200HP 350 V8 Chevrolet Vs the 95HP K in my 22' Sea Skiff? Joe

This is like a multiple choice test this morning, but I'll give it a shot.

Based upon a 17' CC Sportsman able to make 36-MPH on 95-hp, I would think your Skiff, which is probably a bit heavier, with a slower hull (not as flat), and with more wetted area, would be able to make it to 32-MPH at around 3200 RPM flat out. That is just a guess based upon my association with a 95-hp Sportsman.

By contrast, with a 210-hp small block (listing only 200-hp to be conservative) that same Skiff would probably be able to approach 40-mph with the right prop.

I would estimate it could maintain a 20-MPH speed in the neighborhood of 2100 to 2300 RPM. Since you can get small block power greatly in excess of 210-hp these days, I think you're speed potential is about as fast as your Gold Card and that lapstrake hull can stand. On smooth water it shouldn't hurt anything, but there's no need to abuse a perfectly good boat, as I'm sure you would agree.

In closing, your Skiff would be a "better boat" in a collector's eyes if it had a period motor and transmission. Since there are so many 283 and 327 and Paragon combinations out there today on the market, some of which are probably ready to run, I suggest you take a look at that sort of an insallation rather than goind with something like a Crusader or Mercruiser.

I had a 22' Skiff with the factory 327 chevy motor making 210 h.p. I clocked it at 36 mph with a gps. I got nervous though running the boat at 4.5k for any length of time.
