    Air Trapped in Outdrive...

    ^ Does that mean you don't remove the upper vent plug during the fill.? That seems like it would certainly simplify the whole process... .

    Air Trapped in Outdrive...

    What happens with the pocket of air that gets trapped in the top of an outdrive.? We pump in the gear lube from below, and once full, reinstall the upper vent plug. Then we fill up the gear lube monitor reservoir, which traps that air in the outdrive. Does that air eventually work its way out...

    Alpha One Gen 2 Outdrive Mystery

    Please tell me more about the Two Wire Thunderbolt Distributor Sensor... I'm not familiar with that particular issue, and I'm not sure if it applies to my set up. This boat originally came with a TB5, but was apparently converted to TB4. Here is the previous thread discussing that discovery and...

    Alpha One Gen 2 Outdrive Mystery

    So it appears I primarily need to order P/N-8M0214948.? And that carrier part also includes 8M0214939, 864319, and 8M0142854.? (I will also order the other gear housing seals and water pump seals). .

    Alpha One Gen 2 Outdrive Mystery

    The Serial Number of the outdrive is 0F709127 (the boat is a 1996 Sea Ray). The diagram I posted is for Alpha One (Gen-II) 1996-1997 0F680000 thru 0K999999. I was thinking the problem is most likely with the assembly that includes items 19, 20, and 21. .

    Alpha One Gen 2 Outdrive Mystery

    I'm hoping to get some time this week to try to address this problem. I am pretty confident of my recent reseal of the upper outdrive section. And I know the bellows are all good, and the gimbal bearing is brand new. So I'm considering removing just the lower section with the outdrive still on...

    Alpha One Gen 2 Outdrive Mystery

    Yes, I know, but that usually occurs while we are using it, or right after we use it. :-) This happened (twice now) without it being touched, after sitting perfectly fine for over a month. I'm beginning to suspect it has something to do with temperature... Both times it happened during the...

    Alpha One Gen 2 Outdrive Mystery

    No. Both times, once it started leaking, it ran out in a pretty noticeable stream. I'm certain it went from no leak to significant leak. Kind of like it just burped it out...

    Alpha One Gen 2 Outdrive Mystery

    OK. I will replace them too. So items 36 and 37 in this diagram.? .

    Alpha One Gen 2 Outdrive Mystery

    Yes. Probably a good suggestion. So items 19, 20, and 21 in this diagram.? Still can't imagine what would suddenly cause them to just start leaking...! Boat sat perfectly fine for over a month. Everything bone dry. No leaking. And without even being touched, just started leaking.! It's done that...

    Alpha One Gen 2 Outdrive Mystery

    Boat sat in storage for months last year, and then one day, gear lube just started leaking out the water inlet grate. I thought that meant the vertical driveshaft double seal had failed, so I replaced it and all the other upper unit seals, along with a Speedi sleeve on the yoke surface, and a...

    Fuel pump cutting out, 4.3 merc

    I don't think it uses the oil pressure switch to start. It only uses the oil pressure switch to stay running. During cranking, I believe power is applied to the fuel pump from the starter circuit. So the fact that it doesn't restart at all means its likely not the oil pressure switch. In other...

    Strange Previous Owner Hack Job..?

    . OK. Thanks guys.! I guess I don't really have much choice but to live with it the way it is. And I'm fine with that as long as the commanded spark advance is roughly in the proper ballpark. Unfortunately I have not had an opportunity to check any of the spark advance yet. I own two inductive...

    Strange Previous Owner Hack Job..?

    . Yes. It's looking like it originally came with a TB-5 and someone converted (retrograded?) it to a TB-4. The odd part is it appears there is no knock sensor anywhere on it, and no knock sensor module. I suppose those could have been removed when they performed this modification..? It DOES...

    Strange Previous Owner Hack Job..?

    . I believe it is actually connected to a Thunderbolt V ignition module... It's a small flat square mounted on the rear of the distributor housing. .
