    Why do they make 12 point sockets and wrenches?

    Head bolts are often 12pt and many other fasteners.. 12pt otherwise fits over the hex easier, which works if it's a low torque application. 12pt will also grab a square head unlike a 6pt. I tend to only buy 6pt, but have 12pt as well because they have uses

    CCA for a 30hp 2 cycle Evinrude tiller

    trolling motor almost automatically needs something that will take deep cycle, as long as you have a battery that can deep cycle your good. A dual purpose battery can do the trick

    CCA for a 30hp 2 cycle Evinrude tiller

    300 CCA will spin it over without an issue.. FWIW I start my 20hp Johnson on the stand with an Everstart U1 lawn tractor battery. But a battery with such low capacity will also not have a lot of amp hour capacity at all

    Carter Fuel pump

    You can buy a rebuild kit at Napa for $20 or so... Be sure to change your oil given mechanical fuel pumps can fill a crankcase with fuel before they show external leaking

    Force Chrysler 35 hp, pistons.

    Many of the piston companies in the USA will do custom pistons. Weisco will do custom pistons and also do outboard pistons. they could make you a set. But will need your dimensions and might even need an original to go off of so they get it right. It won't be cheap

    Is my 77 Inline 6, 250 CID, 165 HP a GMC or a GM Chevy

    GMC used the V engines until 1974.. The 250 integral head was used after 1975 on most trucks. If you needed a good short block, it would work in a pinch. separate intake heads are not too difficult to find.

    Is my 77 Inline 6, 250 CID, 165 HP a GMC or a GM Chevy

    Some interesting information on the GMC engines https://en.wikipedia.org/wiki/GMC_V6_engine of course, none of this is actually boat related

    1992 Bayliner Cuddy 3.0 Mercruiser

    It's not a lot of motor for that boat. 4.3L V6 is what it should have. But it will make a good beginner boat if it's solid and checks out. Bayliner built price point boats, and one way they did that was basically selling boats with smaller engines than they should have, and optioning larger...

    Is my 77 Inline 6, 250 CID, 165 HP a GMC or a GM Chevy

    I don't think brand is stamped on any engine from the GM umbrella. When Chevy was using the 250 straight 6 in the trucks, GMC had a 305 V6 and a 351 V6. Stopped in the early 70s. Before the V6 they had the Jimmy straight 6 that was 302 cid or 265 iirc. They did v12 engines as well which were 2...

    Is my 77 Inline 6, 250 CID, 165 HP a GMC or a GM Chevy

    Gmc until the early 70s had their own engines. And through the 70s had bigger engines for big trucks. Gmcs first v8 was a Pontiac.. GMC engines were never used in boats

    Mercruiser 470 vs 140

    They are very different engines. One is more or less 1/2 of a 460 made of aluminum. The other is an industrial GM/ Chevy engine

    electric start motor for Tohatsu 8, 9.8 hp 4 stroke

    They are/ were manufactured. You will need the motor, bracket and flywheel just to even attempt to make it work. You need a lot more than that to make it work factory like, but that can get it spinning over for you.. Keep in mind you need to find the electric start model similar to your motor...

    OMC to Mercruiser!

    Your marine 350 if it runs good can be worth hundreds to a person in need of a good 350. If it runs good in a boat, it'll run great in a car. You could try to find a cracked block 5.0L or 5.7L boat. That will give the correct drive ratio and you could use your good long block. However, it would...

    Sear 217 58580 4 horse

    The powerhead is a techumseh I think, and you'll probably find most of the parts you need brand new, being the only thing you wont find is a jug and it'll have to be bored or find used. It's a lawnmower engine though so you will find one... It's going to cost wayyyyy more than it's worth though

    Mercury 2+2 introduced?

    I was basically given a '01 125 2+2 for a small fee and basically getting it off the owners boat so he could put a 90 'zuki on his boat.. He hated the 2+2 and the surge when the other 2 cylinders lit up. He could not troll the way he wanted to with it.. I never ran it before making a little...

    1988 Merc 5.0XL with alpha drives engine replacement suggestions

    My old bossman made me fix a mid 1990's Chevy 2500 w/ 5.7. The intake gasket had blown and dumped the contents of the radiator into the oil pan several times over. Owner ran it as a wood truck till it got hot, and then filled it up again with straight water over and over again never checking to...

    1988 Merc 5.0XL with alpha drives engine replacement suggestions

    Get it going cheap. Buy a good used truck motor, swap gaskets and cam, freeze plugs in your garage. Your engine should have the '87-'95 intake pattern. If it does not, then just re use your heads as well.. Prepare to upgrade to 5.7's when you can
