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

yea i'm sure glad i found it too ;D...i think i was very lucky i didnt blow another motor......i should have it back together and in the water to test by end of the week....i couldnt do anything today i rake and bagged leaves in the front yard...19 friggn bags!!...tommorow is back yard.. :o
 
update:....went out and did a back flush through the thermostat housing tonight..... :o holy beach balls batman...a ton more sand came out...took off LU and took apart waterpump...full of sand also...everything is clean and flushed now and i got the next 5 days off!! but of course my luck hits again ....ALL marine parts stores in the area are closed till jan 2nd!! so i have to wait till then to get a waterpump gasket! :(

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