My Trojan boat doesn't exist?

[AlphaJustin]

I keep searching Google for specs and other info and it seems I'll never find wiring diagrams or anything informational on my boat it's a 1972 Trojan F-25 according to decoding the working HIN but there's nothing coming up when I search for it. Any ideas?

Not sure about the "F" designation, and HINs would have been a little shaky in '72. But there's some specs on Trojans HERE. If I follow/remember right, Trojan was combined with Bertram yachts and eventually just became Bertram (both were owned by the same company). You might try contacting Bertram and see if they have any ideas.

After that, you'll probably not find much in the way of schematics. Boats are typically "rigged" separately from their manufacturing (maybe not as much in yachts, but the idea is still similar). There's likely no "manual" for your boat. Only a manual for your drive line.

I think you are going to find you have to search on specific things. Example, throttle cables for the year and make of your motor. Your gauges will have a manufacturer printed on them, use that as your search argument. Its my feeling the boat manufacturer just make the shell and put gauges, windshields, seating and electronics from other manufacturers in the boat. That's why you really don't get a manual but a brochure of your boat and nothing specific

Just my 2 cents worth.

Thank you guys as for the F I was going off something I found online for decoding hin and the registration. Not even sure it matters. I really just need a wiring diagram the P.O. hooked up one of the batteries backwards and released some gremlins. I at least have a place to start now thank you.

I did that to a car,,,, once :facepalm: what a mess and you know as soon as you do it... funny smell... then the oh no what did I just do....,.

I picked up the remnants of that it was the secondary battery too so the engine still started for him but everything else suffered.

Google search only took me a few minutes. These guys have lots of stuff, including complete specs/owners manuals for $180.00

Friend had an F-25. Nice little boat. His main complaint was that the rudder was the size of a napkin. Backing it was a bear.

I actually opened a similar thread there they are also convinced my boat doesn't exist and I am wrong. I have been on this forum a long time and know there are some very astute members here so figured I would try. The rudder is definitely undersized though.

A wiring diagram will probably do very little for you, even if you do find one. Given the age, there have most likely been many, many aftermarket wiring modifications done by well-intended owners with no electrical experience.

Smokingcrater I didn't even think of that but really my problem should be in the grounding spots and fuses and those should be the same? Ugh I hope. Thank you though for the heads up.

nope... None of those would be well documented if at all in the manual that came with it. I've owned numerous boats of that vintage, every single one had previous owner issues near the fuse box. (either jumpering multiple circuits off one fuse, adding new stuff, or just bypassing in general.)

Honestly I'd just start a thread here detailing your issues and most likely there will be tons of advice. Given your boat and assuming it is an inboard, I'd first look at any circuit breakers on the engine itself. Then break out a multi-meter and start following the leads.
