When I am in forward gear, the motor will rev to about 1200-1400 rpm, then it will chug and drop to about 900 rpm. Could this be because of the red shifting cable? The boat is a 1972 and who knows if it has been changed.. I don't know much about boats, but am pretty mechanical. Thanks in advance,

Logan

Not sure what the problem might be. Probably not the shift cable. Volvos don't have the same shift cable issues as Merc.

You don't give any motor info. Give us some details to work with. A little back round might help. sounds like a fuel/carb issue to me.

It's an aq130 c with a volvo/chrysler 270 leg.

I don't think it's a fuel/carb problem as it feels like something doesn't engage fully in forward gear. I may be wrong.

Could it be something with the prop not hooking up? I heard that it may be some sort of "clutch" that goes bad if you hit something. Someone told me its for when you run up into weeds or hit something to take the pressure off the prop/shafts?

I find it amazing the things people "Hear".

The props do have rubber hubs in them, but they either work or they don't.

First, check the gear lube in the drive. Water in the oil will cause the cone clutch in the upper gear box to slip at times.
Also pull the back cover off the drive and shift gears and make sure the shift mechanism is going all the way into gear.
