Does anyone have knowledge of the construction of older Hunter transoms. My inboard engine is no longer operating on my Cherub. 25 1976 and i want to install an outboard motor. It seems the inside backing of the transom has some sort of insert covered with fiberglass (looks factory). If so, is this pre-install wood for an outboard motor? Or, should I install some wood backing on top of it? Any Cherubini Conogscenti welcomed, thanks.

Call Hunter?
Possibly someone at Hunter remembers how the H25 was laid up. My guess is that it is solid fiberglass, the same as the rest of the hull. And since most H25s were sold as outboards maybe the transom is strong enough. The current boats and my own 1979 H37C are laid up in the mold with the transom as one piece. The Cherubinis were all solid. The current boats are cored above the waterline I think. Regardless I would glass in a large backing plate across as much of the inside of the transom as I could fit one. Use at least 1/2" plywood. And if I could reach the corners I would glass in cloth reinforcement. That would be a second and poor choice in my opinion. Best option is to fix the inboard.

Had ocassion to hang a 4 stroke on my 81 and was worried about the extre weight. Found 1" marine plywood with 3/8" glass on either side. Plenty beef. Never thought an inboard h25 was made, but if I were you I would get that old motor out of there or your trim will be for crap. Hope this helps, Regards, Jim.

Re: Call Hunter?
Thanks for the two options, however, seems no one is willing to fix my inboard, I get responses like it's too old, not enough parts available, it's hard to access etc. I have tried at least five Yanmar repair services, ah well, I guess either I fix it myself (I have no motor knowledge) or I deep six it!

Transom not designed
to hold an outboard engine. Besides, it will cost about as much to hang an outboard as it will to repower or overhaul the inboard.

Thought they all had outboards!
I didn't know any H25's came with inboards, all the ones I've seen were outboarders. I bought my '83 with an old 2 stroke, 7.5 horse Mercury on what I think was the factory outboard bracket. I loathe 2 strokes, so I bought a new Honda 9.9 Power Thrust with 28" shaft & electric start. It weighs around 120 lbs, so I also installed a heavy-duty Garelick mount designed for offshore powerboat use. The engine was $3000 and the mount around $400. I used 1/2" Starboard on the outside & inside of the transom, and it seems plenty strong to me! It has zero deflection in it, unlike the flat transom on my Catalina 25, which deflects under the weight of a Honda 5 horse. I concur that if you switch to outboard that you pull the inboard out & "heal" the holes in the hull. I have a 60 pound air conditioner under the cockpit sole, and the combined AC/engine weight make it tough to trim the boat out properly. I can't really recall, but I believe the transom is plywood cored.

What's up with the diesel?
I had a friend who had one with a 1 cylinder diesel. Pretty good setup. What seems to be the problem with the motor? Those things are pretty indestructable, and I can't believe parts are not available. A piston with liner and rings, a gasket set and some bearings can't be all that expensive. Unless you've let the block freeze and bust, it can't be much more, if even that much. Tell us what is going on and I'll bet someone can give you some tips and avoid the outboard route. And - if you're going to deep six it, do it in my backyard. I'd love to mess with it!

Re: What's up with the inboard.
My winter marina never bothered to fix it so now I'm trapped in the high season where everyone wants their boat worked on hence no work on my engine. I have asked several people and either they're too busy or don't want to work on such an old engine or believe it's too hard to get to. I hate to ruin the big boat feeling on this vessel but I'm not missing another season so, dam the torpedoes, full outboard ahead!
