LostPiker Posted September 10, 2022 Share Posted September 10, 2022 Had the boat out today, 10 mins in, steaming about 18 knots engine rev increased along with high pitch squeal and slowing down. Throttled back to neutral and killed the engine. We checked the prop was still there, wasn't snagged on rope or net. Put it back down, restarted and into gear, same squeal, no progress and it didn't seem the prop was spinning. After a sea start tow back I ran it up on muffs and the prop didn't spin in neutral which it normally does, slowly but it did turn. When the engine is off and in gear the prop turns easily one way but not the other. Will get back down to it soon and take the prop and drain the gearbox oil and drop the gearbox off. Seems they have a rubber/plastic hub the prop is mounted on so could be that or the gearbox itself I assume? Any other suggestions? Quote Link to comment Share on other sites More sharing options...
Andy135 Posted September 10, 2022 Share Posted September 10, 2022 Possibly the sacrificial prop hub. But I'm not sure about the squeal. Sounds a bit iffy, like a bearing has run dry perhaps? Get the prop off and you'll soon see if it's the hub or something further up the drive-train. Quote Link to comment Share on other sites More sharing options...

I don't think we tried reverse 26 minutes ago, Dicky said: Prop bush possibly. Do you have another prop you could try? No we don't. Hoping to get down to it today and get the prop off and maybe the gearbox. Can the gearboxes be rebuilt? I assume its much simpler than a car or motor bike box as there aren't multiple gear? Is it more of a transfer case? Quote Link to comment Share on other sites More sharing options...

Pretty straight forward, just 2 bevel gears and pinion and a dog clutch arrangement and 2 bearings Quote Link to comment Share on other sites More sharing options...

Sadly not the prop hub. Drained the gearbox oil and the drain plug is covered in iron filings and what little oil there was in there is the special glittery type. Got the lower unit off and trying to work out how it comes apart. Looks like you need a special tool to remove a collar behind the prop?

Got mine with a blunt screw driver and ammer, you could make a peg socket to suit. I have a 60c (twin) and a 55 that may be the same if you need a tool making Quote Link to comment Share on other sites More sharing options...

The manual I have suggests breaking it as a means of removal. Failing that I can make a tool, need to find uses for the new tig welder I bought Also looking for a used lower if I can find one. Any tips for a source of parts if I do rebuild suzook12 1 Quote Link to comment Share on other sites More sharing options...

LostPiker Posted September 22, 2022 Author Share Posted September 22, 2022 update, got the tool but the collar was stuck fast. Removed it with assistance from a drill, chisel and hammer. Tried to get the bearing carrier out with a slide hammer puller and failed. Got a long legged puller on order and will attack it again when it arrives along with a blow torch. Watched a youtube video of someone having to destroy it and the prop shaft to get it out so hopefully won't need to go that far. haven't been able to source a second hand replacement other than based in Ireland and the guy wants €1,200 for it. There is a funny little speed boat thing on a trailer for £2,400 that has a 70hp yam 2 stroke on it so if its hopeless I might buy that and take the motor and hope to get a bit of money back for the rest Andy135 and Saintly Fish 2 Quote Link to comment Share on other sites More sharing options...
Andy135 Posted September 22, 2022 Share Posted September 22, 2022 Good effort for persevering. All else being equal the idea of a second full motor for spares or replacement might not be a bad idea. Quote Link to comment Share on other sites More sharing options...
LostPiker Posted September 22, 2022 Author Share Posted September 22, 2022 Puller arrived today. Tried it and broke it. Going to break out the grinder and welder tomorrow to customise it to hopefully do the trick Quote Link to comment Share on other sites More sharing options...
