Hi Everyone,
It's service time for my 1989 Merc 60hp, same time every year for the past 5 years, I prepare for the half hour job of pulling the lower unit to change the impeller but from what I can tell the driveshaft has welded itself to the powerhead. I can get about half an inch gap with wedges and that's taken 3 hours but it won't shift more than that without the feeling that something's going to break. Has anybody got any suggestions? Will I damage the gearbox if I put too much tension on the driveshaft? I wish I could get some penetrating oil up in the splines but there's no access unless I start drilling! Any help greatly appreciated as always.
