It seems as though no matter if i just start it up on a cold morning or at the launch after a good long run, my prop always spins when the motor is running and in neutral, i would have to say that at idle it spins about half the speed it would spin if it were in gear. it is enough to slowly put put my boat around when bowfishing. does everyone else have this problem or is there something i can adjust to fix it?

It will spin... Spinning is normal. I notice each time I put new grease in the lower unit axle tube that it will slow the spin of the prop... I usually change my axle tub grease every 15 hours quick & easy and keeps everything nice lubricated. When was the last time you changed your output shaft grease?

there is an air gap adjustment on that clutch to adjust how far apart the plates are when not engaged. i read it on the www somewhere but now i cant find it though

WestEnd it's probably been about 45 hours since new grease
autogateman that would be very interesting if you happen to find it sometime

You need to purchase some Amsoil Liththium Grease Water Resistant...

Check out my detailed maintenance in my signature it will walk you through everything about the GTR...

not sure if gtr clutches are the same, but heres an example of clutch air gap setting.

First of all if your seals are good you wont lose any grease. Keeping the LU greased is good practice, But the MAIN reason the prop spins in neutral is a form of "fluid coupling" that happens in the transmission. Most of the time is from having a little too much oil in it. The crankshaft spins the planets on the tranny and the lubricating fluid carries the outer Shell/ring gear around the planets that is bolted to the upper sprocket. This is what causes the prop to spin in neutral.

And all this time yall argue with Go-Devil owners about needing neutral, when you don't even have it yourself? lol


Also sometimes on my old PD, the prop would spin vry very slowly in neutral, but not on the new one.

I've had that happen to me coe and to the dog, if it would have been direct drive would have been worse

Ive seen a few outboards, that slowly roates at idle if running them on the muffs. Just run the SOB and have fun.

Thanks fellas Ima see if I can do anything to help it out ...and change my grease

I knew that one - but figured if I posted that it only
happens on the GTR and not the GT it would just start
a bunch of chit....

Glad he found out it is normal and that he is behind
on his maintenance too....

Even the GDSD wants a pump or two from the grease gun
every other month or so --- LOL
