P22 loss of drive

Took the P22 out today and on way back in engine revving but only getting 6 knots. Thought I'd picked up a plastic bag or the like, but prop clean. Shaft out of the gearbox increased rotation with the increase in engine revs, but still 6 knots. No cluncks or bangs. After a short while tried opening up again and back up onto the plane. Then back to 6 knots. Can anyone tell me if the prop has a bush in it and is this likely to be the problem? Here's hoping it is the prop!!!!!

I'm no P22 expert, however one that I used to drive quite a bit lost a whole prop blade before any bush went, so I suspect the answer is no.

Thanks for that! I'll have to have another drink and ponder!

and see if the gearbox oil pressure gauge drops when it starts slipping.

Nope - gear oil correct level and pressure high (no change) when it starts slipping. Prop shaft from gearbox speeds up as the revs increase but the prop doesn't go round any faster. So I don't think its the gearbox. I'll get her out the water tomorrow or Saturday and fiddle around with the prop, and see what's what

What prop are you running. Sound like you've spun the middlle out of it

Got the boat out yesterday and it is the rubber bush in the prop. Splined centre stuck on the shaft and the prop pulled off leaving it behind, shreds of rubber all over the area. Now have the problem of getting the centre boss off !!!!.
I plan to get a new prop but is it worth getting the old one re-bushed as a spare? And if so any recommendations.

Heat and/or a mallet or drawing device will get it off. Had the same problem with mine...didn't remove prop periodically or grease the splines. Unfortunately Lancing Marine seem to be the only ones in the country who sell P22 props and last time I heard they were looking about 350 for one. I would also keep the other one and re-bush for a spare.

Don't heat it-you're too close to gearbox seals.

Give it a good blast with something like RostOff Ice-or RostOff Eco then soak it in either corrosion block, diesel or plusgas with a bag round it to stop it dripping out. Leave it for a week or so before trying to remove it.
