I have looked all over the internet to find what the horsepower for a 5.0L Gi Dual Prop. Does anyone know?? I am looking at a 1999 Regal 258 with this engine.. Many thanks
I have been able to find that the 5.0Gi was rated at 250 horsepower at the propshaft. I understand that the DP and SX ratings are the same. Though no longer available, I found a few examples with a Google of:
A 5.0L engine, even with a DP and fuel injected, is on the small size for a 25' boat, so be sure to do a test run with plenty of weight on board to see how it does.
Here is some information on the 5.0GI engine from 99.
5.7 would give you lots more torque, I agree with the skipper, 5.0 is probably the base model power. I'd say you'll get about the same performance as a 18 bowrider with a 4 cylinder. Criuse well enough and probably get a skier up, but may be a challange with a full load to move that much boat quickly.
