Sand in my engine

[trader0817]

Hello everyone,
1997 OMC Evinrude Johnson 115HP v4
Four Winns Jet Boat

Recently took tons of sand in the engine. I’ve been flushing it with the regular flushing kit, the pee hole is clogged as you can see in the video.

Anyway to unclog the drive and the engine itself other than the regular flushing it?

Anyway to access the pee hole to unclog it manually?

Thanks!

If you have an air compressor I’d say disconnect and try blowing the lines out. Had a restricted cooling system on my 95 Yamaha 701 ended up having to disassemble half the craft to clean all the ports. Found a lot more sand and silt then you’d think.

Thanks! I’m also a newbie to boating. Disconnect all the lines in the engine and try to blow them out, right? I have lines muffler-engine, should I try to blow those out too?

This thread explains how it can happen and how to avoid certain situations. I’d start 1 line at a time. If you can find a flow diagram would help. The exhaust I wouldn’t worry about as the engine pushes that clear. Main issue would be how much settles into the engine passages restricting the coolant flow around the cylinders.
