Single 150hp on 23ft Seacraft CC

Those are great numbers, Tim.

Makes me wonder how twin 150's would perform on my 27.

Check that....I need 30 inch shaft motors or I would have to replace my bracket.

Wierd, you would have to go all the way up to the 225 - 350 hp Verado to get a 30" motor. The 150 hp four cylinder would require an extension kit(s) to get to 30". That's not very sporty of Mercury

Ed - Bay Engineering makes 5" extensions for the 4 stroke 150, so you can make them 30". I'm not sure that the warranty would cover it, but there is a guy on the Bertram site running a single 150 on his Bertram 25.

OK Terry #3, a standing start race between your Bertram 25 with the 115 eTecs and the Merc 150 hp Bertram!! It might take a little bit of time to get the the 1/4 mile marker, however it would be a fun challenge to see if you could drink a beer before they cross the finish line

Gillie - I have to use some Tab to hold it up, but it'll hang at 13mph.

I had a single one spooled up to 4750 RPM's and tilted the other one up. Pushed that Lockeed L-1011, wide body, Carl Mosley - Miami to Nassau 6,000# contender 18 knots. In power to weight, it's still hard to beat a water cooled chain saw. Us ol' dirt bike riders know there's nothing like being "up on the pipe".

Quite good, got to be super efficient pulling that off @ 3K. Congrats on the results. Nice calculation.

Thanks Gillie! I'm gonna throw on the 17P enertia just to see what happens. My prediction is 5500rpm with one person. I wouldn't run a 17p except with a light load (1 or 2 people max and fair conditions).

17P enertia is too much for the boat with a full tank.
I could only get 5200rpm and the hole shot was not good with the 17P enertia.

Going back to the 15P enertia.
