Formula 280 SS - 1995 single I/O 300hp
 
Looking for owners, current or past, to tell me about there thoughts on this boat. The motor has 545 hrs on it. do to the season I have not been able to take it out and see how it will preform. What should I expect??? Is it way under powered?? can the stock 7.4 carb motor be rebuilt to reach 500-525hp with EFI? will the B3 hold up to that HP?

Thanks

Jim

42-43mph...There is nothing in that 7.4 you would want to use over for 500hp. Better off finding a "complete" to drop in and save the 7.4 or sell for some cash back.

My choice...

thanks for your reply. what do you think i could get out of my 7.4 on the used market? would you go with the 502 and how would you get it to 525hp?
