I just bought a bayliner with an 89 force 125 and it seems like the cooling system is blocked, I had the lower unit off and the old impeller looks as good as the new one, I changed it anyway. As i was tightening the bolts, i busted one, so i had to take the top of the gearcase off to get to it, can i just put that back on or is there some sort of gasket or something that i have to get? Back to the cooling problem, is there a way to flush or make sure there are not any blockages,
