I've got a Mercury 20HP engine on our CJR14 boat. Its been in storage throughout the winter and we fitted it back to the transom a couple of weeks ago and noticed it was really stiff going into forward and reverse gear. Checked all the cables and they a free flowing and fine, however noticed that the gear lever on the side of the engine is really very tight to push forward or back. It eventually seized up completely and now wont move.
Decided to ensure it wasn’t agearbox problem, so dropped the leg, but it was still seized solid. Notice thatthe drive shaft was also seized, so took apart the water pump housing and foundthe impeller was knackered. Removed it and the drive shaft span freely and withthe help of some mole grips am able to change the gear into forward, reverseand neutral – so its not a problem with the gearbox.
Started to look at the gear shiftmechanism and moved the carb out of the way to get a closer look and found theshift gear to be seized!
I am able to gently tap the gearshift to move it (just!) using an aluminium bar and hammer but its reallystiff/seized onto the shaft/bush. Sprayed it all over with releasing fluid and continuedto tap it to-and-fro, but it’s still stiff.
Thought to see if it had freed itup enough, so re-assembled the shift mechanism, but its still seized solid andhas made no difference. I think the problem is with this gear or the attachedshaft that then connects to the gearbox in the bottom leg.
Anyone got any ideas or had thisbefore???
Really need some help as Ive beentinkering every night this week and running out of time before my 2 weekfishing holiday!
Thanks
