I just bought a 1987 Thundercraft Regency 16ft with a 2.3 liter Ford. The timing belt broke and the boat had been sitting, water got in and locked it up. I now have the motor free but it only turns so far befor it stops. I think it bent the valves. My question is if I go to the local auto junk yard will I be able to use a 2.3 out of a ford truck or car?

not sure if they will swap, but the 2.3 in a car doesn't bend valves when the belt brakes

Is the automotive engine a timing chain?Rather than a belt?

I need a new prop for a 1989 spectrum. Its 19' with a 2.3 liter cobra sterndrive. The old prop was a 3 blade aluminum and 13 3/4" diam 15 pitch. I'm trying to increase my "hole shot" without sacrificing too much top end speed. I'd like to be able to pull a skier out of the water. Any suggestions?

a 19' with a 2.3 is never going to be much of a ski boat. I would stick with the 15 and just practice the skiing - 2 skis and then drop one if you want to slalom. 1 driver, 1 spotter, 1 skier...leave everyone else on shore.
