    Gimbal Install Help

    Sort of a foolish question... how can I tell if the gimbal has fully seated? I assumed I would hear the sound change when it was driven all the way at the back, but I guess my ears are not as good as I thought because I don't hear anything different. I (stupidly) did not measure any distances...

    Antifreeze under stairs

    Hi, Was looking at a Larson cabrio. Housed beneath the stair going down into the cabin are several hoses and pumps. There is also a bunch of antifreeze sitting in there. I assume the pumps and hoses are related to the bathroom/shower system/drains. Someone at the marina got the boat ready for...

    Options to repower a 33' Larson

    Hi all, Contemplating my biggest project yet. Found (what could be) a really good deal on a 330 Larson. However, it has no engines or drives. Was originally set with a pair of Mercruiser 7.4 MPIs and Bravo 3 drives. Just the transom assemblies, exhaust y-pipes and steering assemblies are left in...

    What are these small cracks in hull?

    Was looking at a 2002 Glastron 250 cruiser today as a new potential toy. The port side has cracks like this (see attached photo) running front to back. They extend mostly down to the keel as far as I could tell. Boat stored in a barn, wasn’t the best visibility. Running my hand over it I...

    4.3L Water Circulation Diagram

    Sorry I meant the spark plugs. Pulling the spark plugs was part of his diagnostic to see why it wouldn't start, and then he left the spark plugs out for over a year while the boat sat. And yes the thought did occur to me that while PO was trying to start it, he left water in the manifolds...

    4.3L Water Circulation Diagram

    Thank you for the replies. I bought the boat already winterized. It was done professionally but 2 seasons ago. Guy I bought it from said he couldn’t get it started last spring, got busy with other stuff and just left it in storage. I bought it under the assumption the engine would need to be...

    4.3L Water Circulation Diagram

    Hi, I have a Mercruiser 4.3L V6 #0M676089 Does anyone have a diagram of the water circulation? I am getting water in the oil. The boat was winterized and I haven't even run it long enough yet to have circulated the anti-freeze out of the block. Does anyone have a diagram of the water...

    Water Circulation Problem - 5.7 raw water cooled

    Hi all, Recently I dropped a new 5.7 vortec long block in my boat. Was out the other day doing some testing and tuning and the starboard riser got so hot that it ballooned and melted the exhaust coupler on the y-pipe (also the flapper is gone- I presume it has melted/fallen down). Water was...

    New 5.7LX No Start, Backfire/Sneeze

    Good evening, what started out as a smooth operation has turned into an extremely frustrating endeavour. I need some outside counsel before I lose all my hair. I bought a boat with a blown motor - a 5.7 LX non-vortec with a 4 bbl carb. I replaced it with a 5.7 long block with Vortex heads. It is...

    Ski Locker Hatch Trim

    Hi all, just picked up a new project. A 98 Maxum 2300 SR. The item giving me the most difficulty is the ski locker hatch. It is missing. I can easily build one out of wood or a composite (HDPE comes to mind) but the problem I run into is I don't have an aluminum trim ring, which is what...

    Oil Pressure Issue - 4.3

    Hey all, I've got an oil pressure problem with my GM 4.3 Vortec (96+). I recently dropped in a used motor into my boat. Hooked it all up and fired her up. Started up fine, good oil pressure, just needed to be timed and idle adjusted. Ran for 10 mins at fast idle then shut down. Went back next...

    Which Coil - External or Internal Resistor?

    I've got an 2001 Mercruiser 4.3, I think it is Thunderbolt IV ignition system (only ignition control module on exhaust manifold, no knock control module). Can someone confirm the coil that I need? I believe it is a 12V internal resistance type coil that I need. My friend gave me a 12V external...

    4.3 Marine to Auto Block Swap

    Hey all, I've got a 4.3 ('01 vintage) Mercruiser with a cracked block. My plan is to swap it with a block from a Blazer or Jimmy of the same year. I'd pick up one of those SUVs, remove motor, scrap car. I will leave the internals in the auto block, and swap everything else. Cam, heads...

    Potential Bow rider purchase - a few q's

    Hi all, Looking to buy a bow rider for the summer. Already looked at a few and they were a major disappointment (and a long drive). Anyway, i have found another that piqued my interest, an 01 Bayliner 195 classic. I asked the usual questions about drivetrain maintenance, interior and floor...
