Honda BF90 Main Tilt/Trim Ram leaking – No seal kit available from Honda only a new

[Skinner2019]

Hi all, I'm a new member who has been browsing the forum for all your useful advice pre purchase of my RIB. Having completed two weeks in Falmouth (had an issue at the end but let’s not mention that…very nice chap in a twin engine rib towed us in) i have now discovered the main lift ram is leaking on my Honda BF90 - circa year 2000 off the top of my head.

It seems the main ram does not have a replacement seal kit; you have to order a whole new ram from Honda at circa £400. I have trawled the forum but cannot find a thread and also the wider internet which has only thrown up a chap who ended up removing it all and then paying for the whole unit. Has anyone found an aftermarket alternative...do the Yamaha parts fit etc.? Any help would be gratefully received.

Iirc some pals fitted a Yamaha trim unit to a honda 150 a few years ago but ive no idea how hard or easy it was.

If I was in your shoes I'd take the unit off and take it somewhere that repairs hydraulic rams, not a fancy Pirtec type place but an older established engineering shop that deals in digger ram and hydraulic repairs. I've had a few hydraulic things repaired over the years and the right guy can usually make & or adapt the parts you need

I find getting in the car and walking in with the item in your hands gets a better response than phoning and trying to explain

Thanks Beamishke, that is indeed plan B if there are no alternatives. Hopefully an old boy will take pity at a local shop. Still surprised Honda haven’t made this a serviceable part.

Built in obsolescence!
Keeps the new sales targets up

Going to the local hydraulic place would have been choice A for me

There always a way to repair. Hell I rebuilt my Tohatsu trim motor with adapted carbon brushes for a Suzuki 125cc motorbike and a spring from Hornby train set! Yes you read that right.

This any use?
