My gear box is buggered the pin that selects gears has dropped out or something and i do not know what to do or how to fix it, i have been told the only well to fix it would be to cut it open!!!

Please help, if you know anything or of anyone

How much have you been quoted to rebuild the gearbox? it might be better to find another engine depending on the condition of the rest of the outboard but the 55s are getting long in the tooth now. Keep an eye on Boats and Outboards and e bay, but tread carefully with old engines.

One final possibility is a Mariner 55 gearbox might fit but you would need to check by fitting it before buying it.

I thought you had one already with a knackered head.....or was it the gearbox that was knackered on it?

Anyway, cutting it open sounds a tad extreme for a lost pin. Can you be a bit more specific or chuck a pic or two at the thread so we can figure out what's wrong?


Did you manage to get the elecrics connected up?

Bill Higham marine has a Mariner 55 (long shaft) for £1100. There are one or two Yamaha 55s on Ebay - unfortunately they're mated to a Fletcher or similar. Hell - still an option though if you want a cheap engine for a £1k.

You'll struggle to find just a working gear-box, especially if you want it soon, otherwise you'll be trawling all the sites looking for a compatible part.

Might be worth cutting your losses and looking to renew? I'd get a quote for the gear-box first. Might be the clutch-dog assembly. No idea how difficult it is to repair.

hey spartacus thanks for the idea i have been thinking of selling the engines an cutting my losses for a while but i have been looking around and there arent any engines at the moment that i want!

Unfortunately not-on an old box you'll be very lucky to get a one off price that (most importantly) he can stick to. It's all dependant on what he finds when it comes apart and how many parts actually need replacing.

How many do you have? Also what's wrong with them?

I pulled the Mariner 55 microfiche form Ishopmarine (all my repairs have been done using the Clymer Mariner book - they are the same engine bar the paint job!) There isn't a huge amount of mechanism to go wrong down there.

What doesn't it do? Does it just not select, is it stuck in one gear, is it just stuck? does it jump out & rattle a lot when you open the throttle in one or both directions? It may just need an adjustment to the mechanism up at the top or your remote cable end fitting!

If you have >1 engine (memory says you have a siezed one?) I bet there will be enough bits between them to get a decent 'box out the pile of bits.

Oh, and probably best not to phone the "cut it open" adviser for a quote!

hey basically i have one engine that is completely seized which i thought had a ok gear box which it does not! The second engine is great it runs. I bought that engine thinking that i had a ok gear box which i foun out was seized. So the newer engine that runs came with a gear box detached which i knew had something wrong with it. The guy who sold me the good top half engine gave me the gear box as well. He said all of that gear box is ok except the pin!? or something that selects the gears, the bit directly down from the prop inside the casing has dropped of inside the somewhere. He said if worse comes to worse i could potentially cut it out fix that bit put back together and it should be fine.

Or he said if i could get all the bits out of the other gearbox off the seized engine that is with the seized gear box as well, then i could potentially just swap them round but i am not too sure how to do any of this or what to do next!!!! Thats my problem now!!! If any of you could help please please let me know i want it fixed!! haha!!

The thing is Yes i could cut my losses but i have looked up and down the blood internet for months now and nothing has come up!!!

Again thanks for all help and as you can see i still need it!!!
Any suggestions would be amazing!!!

Hey guys i have some photos of the two gear boxes the seized one is labeled A and the other is B.

Bascially you can kind of hopefully see the position i am in etc!!!
The gearbox B you can see the cut where the last guy fixed it but the pin fell out i know it looks a bit sketchy but dont worry its all ok, this gear box is good except that problem with the pin or something - i have taken a few shots down in to the gear box where the guy told me you can see where something i.e the pin has dropped out but i did not know what i was looking for hopefully you do!!! Basically have a look let me know hope this helps!!! Oh and the guy who sold me the good engine with the gear box B that i am trying to fixed i am in contact with him he is a nice guy and he thinks i could cut it open again an sort it out, but any way let me know stuff!!!

Thanks again for the help!!!
Oh and if i do cut it open luckly enough my girl friends dad is an amazing welder so i should have no problems fixing the cut bit back on!!!

Ok let me know!!!
