After a long winter of none use and repairs. Fired the boat up on hose fine, put into the harbour running fine for 20 mins. Took it for a steady drive across the bay after about 20 mins we were stopped and the engine cut out. Fired back up and died again. After a few more attempts it was seeming like it was hydro locked just wouldn’t crank.
Once back into harbour found the fuel pump fuse had popped so replaced that and took plugs out and cranked engine a few times. Replaced plugs and engine fired up for about 20 seconds and stopped. Now won’t start again. Any suggestions or thoughts are great fully received.

Did any water come out the plug holes when you turned it over ? Was she winterised ?

What year is the boat/motor? Is this carbureted or EFI?
I'm guessing when you had the plugs out and cranked over the motor, you didn't get any water spraying out of the spark plug holes. If the motor was hydrolocked you would have had a lot of water spraying out of some or all of the spark plug holes.
Have you changed your fuel water separator?

IF this is EFI....do you happen to hear a cyclic tone? Starts low, gets high, disappears, repeats?

Cause if you do....may be your electric fuel pump. That's what mine did when it bit the dust. And it twernt cheap to replace - have a seat when the marina calls you with a quote. Mine was $1k installed - no rebuild kits available. And that was several years ago now.

Hello and welcome to iboats.

As is forum policy, please do not start multiple threads on the same topic. I have merged all 3 of your threads here. It's much easier to follow what's going on in a conversation of it's all in the same place...

Thank you,

The boat is 2000 carb engine. With the plugs out I expected to see water but didn’t see anything. Yeah changed the water separator and plugs. Haven’t changed oil&filter. Just replaced bellows and gimbal bearing. Maybe I will look/replace distributor and rotor. Strange how it fires up fine then just stops and doesn’t want to start again 🙈🤯
