I've seen a b28 with outboards. I agree with everyone else, I wouldn't do it. When I was looking into repower options, one idea a Merc dealer suggested was a single deisel install using a jack shaft to a bravo three out drive. Lots of mods for that install, new fuel tanks, transom reenforcement, eng...

Does anyone know how to calibrate standard gas tachs. I have access to a tach tester that has selectable RPM test points. I guess this might suffice as a transfer standard. Seems like the tach has two ajustments.

Thanks, Rick

Hey, Scooter. thanks for the invite. I actually slip my boat in town creek down the road from reliable marine. Did you replace your tank yet? I just finished my drawings and am having Randy from CMF fabricate.

I decided to use gore packing instead of the dripless. This stuff is incredable. Low friction, lasts for years and eccentially dripless and doesn't scar the shaft. I've run with it for three years and only adjust about twice a season. It's industrial packing. Its hard to find, need to call the compa...

'83, it came with a 190. I looked at an older 28 and it seemed like the aft engine bulkhead was more forward than mine. But basically just need to add bigger saddles on sides.

After much discussion with an aluminum boat fabricator and a local shipwright, I've decide how to install. Both recommended no coating, rather allow air flow around the tank and insolate from any wood structure. I am almost done with my drawings in Visio if anyone wants them. I designed the tank to ...

Capt Patrick. Sorry for the first two questions. Your tips section anwers both those questions. Just need help on the structural questions if possible. Scot, a coast guard report cites a bronze filing left inside the tank as a curprit that cause a hole. Seems like anything is possible when it comes ...

HL, maybe some of the B31 fossils can use the coal tar instead of grecian formula. So no chem etch or primer with coal tar? Any problem areas yet? The fabricator recommended no coating at all, rather carefull install to ensure no static moisture points. He recommended PVC board supports under the ta...

Capt. Patrick, I am preping my B28 for an aluminum tank install. I have a couple of questions based on your tank install tips. I am getting a 190 gallon tank fabricated locally from 5052, 1/4 inch thickness. For those interested, cost is $1800. 1. use 4 lb density foam? 2. How do you prep the tank f...
