Diesel outboard stall

General query. Used a diesel rib for the first time the other weekend. Approaching the jetty I put it into neutral and then reverse to take a bit of speed off the boat and the outboard stalled. No sudden input. Is this normal with diesels, not had it with petrol.

Andy.

Diesel outboards on a RIB? Not wishing to sound disbelieving but are you sure?

Yep, not sure you can still buy one, but they were available some years ago. Noisy brutes and something like only 50hp available. Think it was Tohatsu based.

Yes I'm well aware of them - mostly built by Yanmar. Just never heard of one being fitted to a RIB before for the reasons you just mentioned - very heavy for not much power!

It was a 50 on a 6m+ Humber. By the responses, it's obviously not the norms so the stall is possibly normal but no many people experience it.
