Jeff,

I have a 1995 3300 Coastal with tower. It should be very comparable to your Sports Bridge. Last time on the lift the weight was more like ~17,000# with light fuel and water. Mine had the same GM 6.5’s which were subsequently replaced with 6BTA 300 CPL 1613’s. 300hp@2,800rpm. The transmissions were replaced with ZF-63A’s with 1.56:1 ratios. The propellers are 3 blade Michigan Dyna Jet Nibral 20″ x 19″ with a light cup. At WOT and moderately loaded it will make ~26kts@2,950rpm. It comes up on plane very easily with no smoke. I’m sure it is too lightly propped and I’m leaving a couple of knots on the table, but I like the idea of 20+ year old engines running easy.

I do have some concern over the smaller 210hp engines you have chosen. These boats were all equipped with 340-350hp gasoline or 300-370hp diesel engines from the factory.

If faced with a repower today, I’d likely choose 6BTA 330’s or 370’s. I’d like to see a bit higher cruise and 30+kts top.

Best of luck on your project!
