yamaha 130 dead?

[tarponman]

I have a 1998 yamaha 130 and was crusing at 4200rpms when it made a loadthud then lost speed and rpms then died.When I try to turn it over it just frezzes.You can turn the fly wheel back to the same point and it will crank to the same point.What happened and what should I do?

Welcome to iboats.

Sounds like you tossed a rod. Pull the sparkplugs and see what's on them. If there's nothing obvious, stick a pencil in so that the eraser rests on top of the piston and move the flywheel. The pencil should move with each piston.

it seem the rod went through the block.I just had the head rebuilt less than 20 hours ago.What would have caused this?

The only real way to find out what caused it is to take it apart, which the guy who rebuilt it should be doing, unless it took you 2 years to do that 20 hours.

Re: yamaha 130 dead?

the mechanic wants me to get a new block and piston or find a used one which will be hard here in the islands .Somebody mentioned taking it to a machine shop and having them weld it. Good or bad idea?I still don't have any idea why this happened .To fuel to that piston ,not enought oil or water in the head or who know what...

Very unlikely to have sucess with welding if the rod penetrated the water jacket.
