    Hardin Marine Exhaust on SBC (350 Mag)

    So....... I recently just purchased their Seaward Series exhaust manifolds. They are really nice pieces. Bolts are steel but otherwise a nice kit. Anyway, after removal of original manifold, I noticed that my heads have oval ports but the new exhaust manifold has larger square ports. This was on...

    Boat Wrap

    So, I’m looking to get my boat wrapped. Was wondering if anyone knew the prep for one. Will they strip the wax? I ask because it needs to be de-oxidized for sure but should I continue with polish and wax? Can get by with using just an oxidation remover? I guess I could ask the installers but...

    350 Mag couplers 18643A5 or 18643A7

    Hi, so my coupler has a triangle base but does NOT have the protruding sleeve that has a zerk fitting like on the A5 or A7 . My engine s/n A681758 is calling for 18643A7 which has a new shaft. Is this a conversion kit for the Alpha One Gen One?

    Alpha 1 Gen 1 Mercruiser power steering

    Yikes that does look like a few F-bombs worth. Luckily I have the engine hanging because I changed my motor mounts and transom plate seal. So access required zero F-bombs. Today, I bought the previously mentioned control valve #401-0101 and seals for the cylinder #25-58226A1 on ebay. So we will see.

    Alpha 1 Gen 1 Mercruiser power steering

This thing is buggering up my engine bay. PS booster 57969A12, seal kit is 25-58224A1 PS Valve 816458A1, seal kit is 25-58225A1 I did find...

    So I’m finding a choice between 140 and 160 degree thermostat for this engine. How shall I choose?

    Battery gauge

    So, how has this been working for you. I was looking at all of them on Amazon, Including the one you have. Seems all of them below $100 have very mixed reviews which I take with a grain of salt because I include possible user error. I have a run-about which I keep two batteries just because I...

    Transom plate / Gamble housing through bolts (Alpha1 Gen1)

    I like the idea. I assume you eliminated the anodes then?

    Transom plate / Gamble housing through bolts (Alpha1 Gen1)

    Wow, talk about timing. I kinda don’t want to add sealant and it’s hard to see the entire the gaskets once installed because they are slightly recessed into the housing. So if I don’t add sealant, I think it might be a good idea to re-torque them in 2 or 3 years.

    Transom plate / Gamble housing through bolts (Alpha1 Gen1)

    So I am replacing the rubber gaskets on the 2 lower through bolts. The bolt head has a square to index the bolt and small gasket around it. They seems to be lacking in substance. Wondering if others put sealant on them. I was thinking a very thin coating should do it On both side of the gasket...

    New gimbal bearing, can’t get alignment tool in coupler

    Hi. Having trouble identifying the rear engine mounts. Obviously one on each side. I have a bolt with a washer and a sleeve that comes off. Appears to be another sleeve inside the mounts. Is this the bushing? Is this rubber? Is that what needs to rotate? Or is the thick spacer between the engine...

    New gimbal bearing, can’t get alignment tool in coupler

    Hi. If I rotate (slide) the dimpled sleeve that’s on the outside of the bearing I find a rather large hole which appears to be meant for grease
