Default Would it Work?

What if you had a older 26-27 foot formula, chris craft, that was set up for twin engine small blocks. How well do you think it would perform with a single engine big block? Or do you think the boats are just to heavy for this.

Boomer,
I tried my boat (26 Sutphen) in both single and twin before I bought. Both were used (12 years old) and had stock power, the single was a 330/TRS and the twin was 350 Mag/Alpha's. Simple choice - I bought the twins because I planned to stick with stock power, more or less.
To move the single at a comparable speed to the twins, my guess is it would need 50 per cent more horse power than the 330 was delivering, something like a 502. In round figures, add 7 - 10 thousand dollars to the price of your old used boat.
Buying the same boat new, I would go with a single and I doubt that the construction/weight has changed much. What has changed is the more affordable power options available from Mercury.
Check with the manufacturer to see if they offered a single engine option. You can bet that a twin big block/Bravo combo will be very heavy in that size boat. If my engines blow, I will look into stroked sbc's with as much aluminum as I can afford because I hate extra weight.

also old formula's are biult like tanks. Your not goign to get much speed out of a 330 454. YOu woudl need BIG power. I had a single 330 in my older (heavy) scarab (26 excel, 27' oal) and she barely ran 50 with 330hp. I have a 550hp that is abotu to be dropped in and i am shooting for mid/high 70s.

coincidentally if you interest teh baot is for sale. It shodul be backl together shortly. e-mail me i'd like to deal on it [email protected]
