If you remove the raw water pump you can get at that bolt but be careful; if it's really stuck you could break the crank pulley bolt.
I'd try either PB Plaster or Kroil to dissolve the rust.
Some say that a 50/50 mix of auto trans fluid and acetone is even better but I've never tried it.
A strap wrench on the pulley might be a safer bet.

Can i ask what a great price is on that boat? Just curious....

It better be retail minus the cost of a new engine because that's where it's headed...

There's gotta be a crank bolt you'll just have to get the water pump off . I can't help with that, both boats I've owned have the pump off to the side.

This is what it will look like with the Raw Water Pump removed (which includes the pulley)
The water pump removes with 3 bolts.

The sooner you can get this engine rotating and oil-up, the less work you may have to do. Hopefully you don't need new rings and cylinder honing, however, it is likely you will need to have the heads worked on. So if you can't get it rotating, you should start removing the intake + Exhaust + Heads.

ps: "Running rough because of bad manifolds / risers" sounds like a Bull$#!T statement. Exhaust manifolds could never make the engine run rough. However, water getting into the engine (from the manifolds) could. Sounds like they were trying to tell just enough to cover their ass when they knew it was more serious. Then when the engine sits for a while it locks up due to rust.

However, this is all fixable, and you may have still gotten a good deal.

I was just thinking it might be a good upgrade for me...lol im getting good at this engine removal stuff. I bought a remanufactured marine motor for around 2500 shipping included, with no core charge. If you get in to deep it might be as cost effective to change it.

OK I removed starter and one tooth was damaged hence the grinding noise

Motor is stuck fast, I cannot budge the flywheel either up for down, not turn crank pulley using a strap wrench

Am soaking pistons in oil for the night and will try again tomorrow

would the one damaged tooth mean the flywheel will need replacing? Assuming I get the motor running, if the motor ends up needing replacing, then the flywheel will not me an issue I guess

Hi Rick

a great price on the boat (IMHO) was $18000, 2008 four winns vista 258, I have not seen any for less than 45k for that year.

At least there was enough saving to replace the engine as thats where I seem to be headed now.

I started another thread with pics of the engine once I removed the head, it seems too far gone to me. I would welcome any pointers of solving this mess please

You remove the outdrive first; then the engine will come out.
