I need help... And not - it's not a Bronco -or even a car this time

Yeah, that kind of help too, but that type is not what I came here to ask for

I have a 1966 StarCraft boat that was given to me. It has four-cylinder inboard outboard motor that two years ago ran fine, then last year started having starting issues. now I can't even get it to crank I have replaced the starter the solenoid and the ignition switch battery is charged and I can't get it to crank Let alone try to start

Does anyone want to come help me troubleshoot this thing? preferably someone who has great ideas on how to make This old stuff run.

Yeah, it has points. And no I have not replaced them yet. I figure tune up comes after it turns over

I'm pretty sure we can get food and beverages from my missus in exchange for your expert advice and assistance. I'm thinking tomorrow (Sunday) at this point. Considering we still have Daniels truck torn apart replacing the water pump and I'm about to start drinking.

Does it make any kind of noises? Starter seized?

I can promise you this, there is a lot less stuff I. The way when working on this old boat

Maybe the wires have corroded further down the sheathing?

Can't speak for old boats, but I had the fusible link cook on my rig prior to me owning it.

Yeah, I'm starting to believe this is a likely possibility. The good news is, there is even far less wires in this boat than out broncos ever had.

I don't think there are any fuseable links in the boat at all (thankfully)

So hopefully tomorrow evening I can start replacing wires. Sooner or later the engine will turn over.... Right?

Take everything out of the loop besides the starter & battery to confirm starter turns over. Once this is confirmed I'd start running continuity tests on wires, once this is done check ohms (using standard specs). The prob will turn up in one of these steps.

Can you get the engine to turn over with a wrench? Is the engine seized?

Did you winterize it with antifreeze? (cracked block/rust)

Oh yea!

New starter (x2)..... Nope
New solenoid .....nope
New ignition .....nope
Replaced wires from solenoid to starter.... Nope
Replaced power from battery to starter and ground too.... Nope

Built a ground cable from starter mating bolt to battery ground......oh yea

Pulled new (2nd new actually) starter to test, grounded the case and zoom zoom

Who new, new starter does not ground directly to the block. She's grounded now

Awesome!
