I'm looking at a boat with a 175 EFI that may need a new powerhead , it's 1998 I talked to a guy at Blackbird industries who said if I ship him the motor [ Florida ] he would install a new powerhead , break it in ad send it back with a 1 yr. warranty for $3850.00 . I talked to a local guy who would do the same for $5500.00 I'm in norcal what other options do I have ? Can I go with a 200hp powerhead and use the same lower unit ? Any opinions on this motor I've read a few posts on the EFI motors and the seamed a tad negative . Thanks
