Alpha One Question

[wil7483]

I took my outdrive off today to start a trouble shooting session on my low power issues. I put it on a stand, placed it in forward, turned the prop, counted the rotations of the yoke, 1:1.50 which is correct for my engine.

The question is, while turning the prop should it turn with no resistance and noise? Mine turns if you give it some pressure but it makes this noise almost like when rubber is binding against something. It isn't a grinding noise but more so like I said rubber pushing up against something. Is that noise and resistance the impeller rubbing up agasinst the housing?

Also, I tried to take the top cap off to have a look inside at the gears but I was only able to get one bolt to turn out. The others look to have been already rounded off in the past. Any suggestions?

Heat.

Or leave well enough alone if it isn't leaking. Be prepared to deal with broken bolts in the aluminum.

Or leave well enough alone

i'll second that. it's always a bummer to have to extract broke bolts... besides, ya ain't gonna see nothing under the cap anyways.... except the drivin gear mostly and the drive gear and if ya turn the cap over the upper drive shaft brg. assy...........

a dry impeller can make it difficult to turn the drive shaft.... after i R&Red my impeller last time. with all my might and my best grip on the drive shaft. i could barely turn the drive shaft at all.....
