Re: New Tubby Tug build

ABX or ACX would probably be just fine for a tubby tug as it is a displacement hull, but the BOM lists 3/8" and 1/4" thickness. Good luck actually finding ABX or ACX that thin.. My experience is I could not find it and special ordered marine grade as it would have been special order anyway.. The oth...

Re: Seized up Blue Stripe Merc 40hp looking for a Powerhead

Agreed. The 402 was kind of an offbeat from what Mercury was good at, at the time which was 4 and 6cyls. I think it was their first attempt at a 2cyl 40hp. I think that's what the 2 meant in 402. Hard to get a lot for, not really serviceable nowadays and not valuable either

Re: cloth weight

7OZ is an odd weight. Only place I have actually found it is the Glen-L site. 6OZ "E" glass is far more common and would be what I would use on a regular build. Something like what you want, I would use a single layer of 1800 biaxial cloth ( 18OZ, no mat ). That will give you a great strength as it ...

Re: Flywheel forward V6

You could do it with a 4.3L using stuff for a SBC given they are the same on the front, but what that entails I'm not sure. Flywheel Forward is a pretty specialized setup.. MR Hotrod probably knows better than me tho. You can find pics of a 4.3L setup FW Forward on his website http://www.chelseacoac...

Re: 2 engines or 1 HP

IIRC Mercury says that you go up 1 prop pitch with twin engines, so yes, a slight bit better in theory. Plenty of offshore fishing rigs running twin outboards in the event of engine failure. Not sure it's worth it otherwise

Re: Torque curves for vintage engines?

Yea, the Crosleys are kind of a mystery. I know they were rated for 35hp in the cars but when Faegol ( think I spelled it right ) designed what became the Homelite outboard, he increased the displacement to 60 CID and they were rated for 55hp, but I don't think that torque numbers were ever publishe...

Re: Torque curves for vintage engines?

what engines are you thinking of? Most of the vintage marine inboards were automotive based and the information is out there if you look in the right places. The exception would be the old Chris Craft "K" engines which were Hercules QXLD-5's and were actually industrial engines, yet Diamond T's did ...

Re: 70 hp engine om a zip ????

With a 20" transom, I would say most likely it would take it. The boat would rate nowdays for about 40HP prop shaft/ BIA rating.. When the old motors were re-rated when they went to prop shaft ratings in the 80's, they typically dropped 5-10hp, ex: the old 44CI Merc 500 was sold as a Mariner 40hp ri...

Re: Glass over faired hull?

You didn't need 18oz, and you didn't need a CSM backed cloth either.. CSM is used because it reacts with the styrene in polyester resin to create a better bond. Epoxy has no styrene.. DB170 would have been cheaper and better At this point, just sand and fair it out. Most plywood boats have 1-2 layer...

1961 should be a Cloud White motor. Color went to Phantom black in 1964 at the same time the cowls took a little different shape. Motors made before 1959 were available in colors

Re: Homemade stick welder

$89 if you go to Harbor Freight. 115V Buzz boxes and I've heard they work pretty decent, after all, an Arc welder only needs to carry enough current to make an arc and get it hot enough to weld. It does not matter how it is obtained.. I learned on an older Century 110V Buzz box that would weld nice...

Re: Homemade stick welder

There is another way to do it too.. remove the recetefier from a 100A alternator, whatever is cheap at the parts store will do. Then you need a 115V motor. Hook the motor to spin the alternator, and then wire the alternator so it can excite the field by itself. A 12V DC power adapter wired in with a...

Re: Turbo civic motor as straight inboard or V-drive

You can use anything that you can get USCG rated fuel and electronics for. VW Diesels are used in marine service but are sold by another company so you would need to spend a lot to get actual VW diesels up to spec.. As far as singles vs twins. Many factory boats could come with single or twin engine...
