    yamaha 25 refit

    Welcome to the wild world of the Y25. I've attached a couple of photos of the raw water strainer on my boat. it is mounted on the forward bulkhead of the engine box. The gray valve is a 3 way which allows me to fresh water flush the engine and back-flush the strainer. The hose connection is...

    Sunforce Marine 600watt Wind Generator

    the parts list doesn't break down the alternator, only the assembly. I was hoping to come up with alt. model (AC-Delco, Hitachi etc.) prior to having to measure the existing bearing to reduce downtime. Thanks.

    Hello All, I'll be working on an older Sunforce Marine 600 wind generator in the near future, with an internal noise. I would like to identify what alternator they are using prior to disassembly. Internet searches and customer support has been futile other than schematic and a parts...

    New owner of 'Shamanita' Y25 (SF Bay)

    I Do have the patterns of my boat. I strongly suggest copying your own as they are not symmetrical. I too regretted cutting the floor....obviously it had to be done. I did the floor removal and pattern work / pre-fabrication in the water prior to haul out. Cutting the G20 was a chore done at my...

    Welcome aboard the Yamaha Forum. this is the only active forum I have found for the Y25. We have covered a lot of ground over the years. Haul Out: inform the lift operator of the prop shaft exiting the keel, they will have to sling between prop and skeg rudder. Blisters seem to be...

    Does anyone know the O.D. of the cutlass bearing? while the shaft is 22mm ( 7/8) the O.D. of off the shelf 7/8 cutlass bearing is a much larger diameter. I have no problem turning down the OD. I need the strut I.D. before tearing out the old cutlass. Any help from the Y25 crows feel free to...

    Y26 rig tuning advice

    Hello Hoosgow, I have a Y25. I've attached the Y25 manual that has a good tuning section that works for me. I figure the basics are similar to the Y26. I have Dyform rigging so shroud tension # are irrelevant. I rely more on mast performance in various conditions. I use rig tension to...

    Yamaha 25' ...head?

    US models came with porta potty, Others with Head. my boat has the thru hulls so the previous owner installed the flush head. Use of a bladder on the port fwd compartment works well. Don't use it often but handy when its needed. A well vented and maintained system has worked well with no...

    Rig Tension Specs

    Y-25 PARTS

    Unfortunately he passed away a number of years ago, and yes he was a master metal magician. Any good metal fabricator / welder will be able to duplicate the process. It requires two machined bocks be welded in place to accept studs for bolt mounts. Which y25 did you buy? Thought I new all the...
