Re-powering 1972 SeaCraft 23'...F300?

Terry and Ken are right. That's the same reason I'm still running my 2003 EFI Merc. It's been very dependable and for the small amount of time I use the boat it makes no $$$$ sense to hang a new $20,000 engine on the back. Simple math, $20k divided by $5 gal for gas = 4000 gal. You can go a long way on 4000 gallons or until your engine dies. However if you use the boat A LOT and want to improve your fuel efficiency, you may want to trade while your trade value is still good.
