Snipe, you have inspired me to sand, fair and paint.

Ttownthomas

My B25 project is in a holding pattern while I await a Coosa delivery. I started to think about how to refinish the inside of the v-berth. The original (I assume) headliner is a wallpaper-like vinyl with a very thin weave pattern to it hat is clued to the underside of the core and to the underside o...

Original literature says 112 gallons. here is a snippet. PM me your email address and Ill send you the pdf of the owners manual.

Ttownthomas

Funny, with those heavy inline 6's in my boat I'm trying to move weight forward. I'd love to see your drawings. Still have my email address?

Ttownthomas

I figured they were over seas when he said 750 litres. Lol.

Ttownthomas

Did you compare prices between aluminum and plastic tanks?

Ttownthomas

I recently stumbled across some companies that make custom "welded" plastic fuel tanks. I assumed only aluminum tanks were customizable for reasonable money. I think I can get about 110 or so gallons (or maybe as much as 130 if I relocate my batteries) with a custom tank in my B25. Does anyone have ...

Ttownthomas

Yep. Understand all the arguments but all the parts are bought already. Thanks for the info on the stringers!

Ttownthomas

Whats wrong with the t-handle drain plug?

Ttownthomas

Lol. All of these things have crossed my mind. The miser in me wants to keep the old American iron. Flinstone simple motors. Allready: Replaced Risers and manifolds, fuel pumps, rebuilt carburetors, Had starters and alternators rebuilt. Just have to replace the water pumps and should be good to go. ...

Ttownthomas

A surveyor blessed the hull and I have looked for signs of delamination but haven't found any. Just figure better to check again while everything is apart. The transom was still solid but since the bottom of the keyholes had bare wood I could see they were wet once the transom assemblies came out. I...

Ttownthomas

My companionway door and hatch and all hardware are sitting in my garage. Do you still need info on this? The boat looks like this right now:

Ttownthomas

Every time I make progress it seems I take 2 steps backwards. Not complaining. I enjoy the journey. I was trying to nurse a B25 back to health but once I got down to the outdrives and transom assemblies I decided to replace them. So I hit the reset button and had the motors pulled. Then I discovered...

Ttownthomas

Whats your steering issue?

Ttownthomas

What about those deck hatches outboard of the stringers? That also does not look stock I don't think. More evidence the deck has been re-done

Ttownthomas

fantastic work

Ttownthomas

why not get an inboard B26 moppie and put a tower on it. The motors are spaced like the 31

Ttownthomas

A thought: With the movement of the trim pumps and the removal of the swim platform perhaps the boat will have a better stance in the water.....Moving the scupper holes "up" a bit.

Ttownthomas

I have been (slowly) restoring a '72 B25 Moppie i/o. Pretty much all of the engine work (manifolds, risers, fuel lines and pumps, rebult carbs, new cap, rotor, plugs and wires) has been done now. I have also repaired the trim tab system, replaced the mechanical and antiquated power assisted steering...

Ttownthomas

did you get this solved?

Ttownthomas

looking great

I assume you know better than most. Sorry to hear it. Lol

Ttownthomas

That looks great. Which model is it? I've owned a 25 sport fish with the 470's. At least I think that was the number they were about 175 HP apiece. My dad owned a Sport Fish with the 165 HP. Isn't that what yours are? They were great little engines. I never understood why they quit using them. Its ...

Ttownthomas

I forgot to ask in my post. What is a good chemical to clean all the black muck from the glass so I can get that bertram green back on the inside of the hull? I assume I need to scrub brush it with something.

Ttownthomas

I have been busy removing antiquated systems: Removed: 3 transducers, broken Autopilot, clunky Mechanical steering, Leaky power assist steering, bilge pump, 1984 halon system, very old engine synchronizer, Broken marine radio, Weeping and old trim pumps and broken mechanical senders, blowers and hos...

Ttownthomas

Congratulations!!! Looking great

If you PM me your email address I'd be happy to send the files I have.

As for the inserted drawings: I use sketch up free. the web based version and there is an "insert" menu option in the menu that is a picture of the folder.

Ttownthomas

Happy to help. Ill circle back this evening.

That is what I assumed originally but after measuring it does not seem that there is enough space stbd of stbd Drive for the ram and the extended shaft to fit. I was hoping someone could confirm if this application works on the bertram 25

Yes, this is the drawing I referenced in the above PDF. But does that get installed on the port or the starboard side Drive?

Ttownthomas

I have removed the power steering from my MC-1 drives and am planning to upgrade to seastar hydraulic non-power assist. The diagrams in the seastar installation manual are lacking detail. Sorry if this is simple stuff I'm just having a hard time figuring out how sea-star intends for me to set it up....

Ttownthomas

Is the ram mounted to the transom or to the mounting loops in the MC-1 inner transom assemblies?

What model number is on the ram?

Sorry for all the questions.

Ttownthomas

Good to hear. Thats the route IM going! Do you still have MC-1 Drives? If so is there any way to get a picture of how the ram is installed? Or at least tell me what side it is installed on?

Ttownthomas

Marks. Do you have power steering or full hydraulic?

Ttownthomas

Oh. You had alpha I drives. I have MR-1's. They appear to have different setups. Do you still have your drives and transom assemblies?

Ttownthomas

It attaches where? To the aft motor mounting bolts on the stbd motor? Any chance you have part numbers?

Ttownthomas

I know only smaller Bertram’s were built with sterndrives. On my b25 i’m wrapping up the engine refurb and will move on to steering next. She has original looking mechanical steering with a very leaky power steering system run off the stbd engine. How should a properly functioning system feel? Assum...

Ttownthomas

wires that had 1 end completely unhooked: 3 old unused transducers, 2 sets of vhf radio power and ground, loads of ac wire with a rusted convertor, a broken autopilot, 2 sets of unused stereo wiring with FM antenna wiring and a few sets of wires that went to nothing.

Ttownthomas

Newly acquired B25 had a huge wiring mess. I simply started removing wires that were either connected to the old unsafe AC system, connected to nothing, or connected to something that did not work. Not sure how many hundreds of feet of wire I've removed but it is quite a bit. https://live.staticflic...

Ttownthomas

Thanks for the tips! Any idea where to get a tank pressure tested?

Ttownthomas

So...I was hoping someone would pipe in with some insights on this gas tank. It looks to be of high quality but there is no tag on it of any kind. What does that mean?

Ttownthomas

I was planning to replace the tank. I have no attachment to any particular tank material. By bladder to you mean that it inflates and de-flates as you use it? Or do you just mean a plastic tank? the dinette I have in mind wil convert from a dinette to a rearward facing lounge and double as a kids bed.

Ttownthomas

The B25 furniture was rotted, ugly and old. By that I mean the galley/captains chair combo and the dinette. I carefully removed them today in such a way that they can be used as templates. The stainless water tank left rust spots on the deck below. What is a good cleaner to get rust stains off of fi...

Ttownthomas

Its hard to get to those passages but I shot a hard stream of water in there last night and it poured into the bilge from both sides. Not sure if it was clogged or not but it is clear now. After I get the dinette and galley up (they are all rotted anyway) I will have better access to to the center o...

#1: I don't like that hole in the deck. It's outboard of the stringers. If the passage ways are clogged up, the boat will hold water.

Anybody know where the passageways are?

Ttownthomas

My threaded hull drain is under the starboard engine, right of the center stringer and about 10 inches forwards of the transom. You remove it from the inside via a t-handle type mechanism. I’m not sure if this is standard or was added at a later date. Apparently it was standard. Mine has it too! Th...

Ttownthomas

LOL. Look what I started. I'll figure this one out myself. I can't rephrase without cracking up.

Ttownthomas

Does anyone recommend a brand or style of water muffs to use on an inboard-outboard? I don't want to starve the dives of water
