My Honda 2.3 has been sunk along with my tender for two tides. Returning to find some very kind people had returned the tender upright and floating however the engine was full of black sludge, Penryn mud. I rowed back to my boat and fresh water washed what I could and it has been left for three weeks. Iam now ashore and have a suitable place to dismantle/repair the engine. I can try myself but I have no experience of this motor, find a good mechanic, (Robin Curnow in Penryn is good but can be expensive) or write it off and sell for spares. What do others think?

After three weeks it is probably BER the salt has probably affected the alloy. However, won't hurt to strip and try repair, If nothing else you will learn a lot about engines!

You could take the plug out and spray some lubricant in . Leave overnight. You never know, It might turn over. If it does turn over you have every chance of saving it.

I have dunked mine twice . Trapped under a drying pontoon the last time overnight . Three weeks is a long time though.

The normal process after a dunking in salt water is to dunk straight away in fresh water. This removes the salt. If you leave it for any period of time without removing the salt, the engine is almost certainly scrap

At the beginning of the year, a chum of mine did a similar thing with a Yamaha 2.5hp. He washed it out a bit, but didn't clean the carb. He brought it to me (as I was bored) and I took the carb apart, saw immediately that it was goosed, ordered a new one which duly came and was fitted. I'd put new fuel in, and a couple of other simple things, and the engine started 1st pull. I adjusted the tickover and it was as good as new. Told my mate, and let him buy me loads of wine. Job done. I'd imagine that yours wouldn't be too far different, and now's a 'good' time of year perhaps?
Steve65 would be worth a PM perhaps?

Unless it’s a British Seagull of course!

Hi, We spoke yesterday I think?.
The engine certainly isnt scrap and is repairable, maybe for run of the mill labour charges it may not be financially viable.
The internals wont be corroded as the oil protects the alloy, no steel liner so no problems there. The only issue you may have is crank bearings. You can push on new bearings but to get to the lower you have to remove timing gear.
It will need complete stripping, degreasing and 100% will need a new clutch bearing.
Good luck with it!
