Hello I have an on going project with a 1977 27ft hunter thats still on jacks but I'm trying to get her ready to launch by June. While sitting for 3 years the cabin filled with water and the engine was partialy submerged. I got the engine running 2-3 minutes at a time this weekend I'll hook up the raw water intake and discharge and let her run for awhile. My problem is the trans filled with water which I have half drained but the oil is so thick its clogging the pump My question is can I let the engine idle with the trans in nuetral to warm up the oil water mix or will that damage the trans. I've been told to flush the trans with kerosene after I drain it but I've got to get that stuff out first. thanks George
