Hey bud, thanks for the reply. As far as i know the boat has primarily been used in saltwater. I know that the lack of usage is concerning, but the last 5 years i have been taking care of the boat, never took it out of the harbor, but i have ran the boat a couple times a year just to keep things moving. Earlier than 5 years, i have no idea.

i do know that they run well with the boat on the trailer with the hose. The boat has lived in Southern California for the last 10 years, but before that i also dont know. I jumped and jumped on the motors and did not see ANY flex. i dont know if the transom has ever been rebuilt, but it does have what looks to be a custom stainless motor well cover about 1/32" thick that wraps the transom well. Upgrading from a 17' whaler, i believe that anything will ride in rough weather better.
thanks matt
