alil blockage?

[Kajun]

i just wrote this post on another forum..so i'll just copy and paste it to save time lol



"well a week or so ago..i installed a new waterpump because i was getting a overheat alarm when i hit 40mph, i dropped boat in water to check it out...got out about 50ft from dock.. hit a sand bar then broke my steering cable trying to get off it...made it back to dock..no symptoms of overheating or blockage...

yesterday i installed a new steering cable and decided i'll go fishing and test out the water pump again ..dropped boat in water last night....warmed her up for about 5 mins.. took off..got outside of the no wake zone and hit the throttle...jump up on plane and immediately get a overheat alarm....$#@%!....i knew this was not good...i turned her around and coasted back into dock slowly.. praying i wouldnt blow this motor also.....docked..turned off engine pulled cowling...she was hot!..no false alarm this time.

tonight..i decided to pull the heads to check/clean the water circulation system....wow..there she was...both sides full of sand! blocked up like you just ate a whole block of govt. cheese! before i pulled the heads i checked compression..all good...luckily i seen no signs of damaged cyl's. rings or pistons.

tommorow gonna flush her out and check more passageways...here's some pics of what less than 2ft of water and a sand bar will do to your motor.

You have got to feel better knowing what the cause is? Good luck. Get her back together and there is still time to catch a few Rock ;D

That's nasty, but a pretty easy fix. You'll be on the water in no time. ;)

That's a LOT of sand!!! Be careful not to get any of that sand inside the cylinder.

Measure the thickness and cut your own. The thickness of the gasket is important as it sets the impeller to housing clearance.
