I am currently changing my outboard glastron to inboard. Im putting in a volvo penta 250 4 cyl. Has someone done this before? If so what design is best for the motor blocks that get glassed in the boat? I have heard that the motor will run smooth and you wouldn't even know it is back there.Aposed to an outboard. Do yall think it will be a good setup. I bought a 19 foot invader for 50 dollars because the guy told me the motor was locked up so I brought it home tried to unlock it for 2 days so I decided to take the starter off and when I did I found out that it was froze solid with rust. So after that I found out that the starter was the only thing that was holding the motor. It wasn't locked at all so I got a great deal with no title. But its worth it for all the running gear. It's got a volvo 4 cyl 250 and a volvo penta drive and it has a closed cooling system.
