Thread: waterloged 1300r engine..

waterloged 1300r engine..
a buddy of mine has a major problem with his 1300r
after a days skiing/wavejumping my buds ski started running like a dog.
the thing was misfiring & making no power..!!
we make it back to the slipway get loaded up and head back to his place..
so while we're flushing the ski's out he decides to pull the sparkplugs to check them..!!
so when no2 plug comes out there's steam? coming out the plughole...???
my/our first thought is Oh SH!T.. this ain't GOOD...
so off comes the head.. the thing is FULL of water, we could see water up over the ports...
our second thought is WTF..??? this ski has less than 20 hours on it., its an 04 model...
so the big question is what the hell has happened..??
is it a/ a blown head gasket..? b/ a cracked jug..?? c/a cracked head..?? d/ i'm out of ideas help..!!!
anyway my bud is a mechanic/garage owner so the ski is going to the garage tomorrow,
to get hung upside down on the crane,
we spun it over a load of times till there was no more water droplets getting on the pistons.
then it got filled with a mix of oil/diesel @ 50/50 mix in an effort to save the crank bearings..??????
what i'm wondering is the pressure greater on the flush hose or out of the pump,
seems this might've happened when we were flushing so maybe a fault waiting to be found..
ok guys looking for advice/ideas

With that much water, I'm thinking it happened on the flush hose. You can not have the hose running without the motor running! I would put the head back on and run the snot out of it NOW.

I've just realised why you "CAN'T " flush without the engine running,
Don't know why i didn't KNOW this but.. must've been thinking cars and closed loop cooling..
OK as everyone here knows when the hose is running with engine OFF the water will fill the waterbox,
which when full... will backup into the exhaust,
which will then fill the cylinders and crankcase...
you have NO idea how much of a moron i'm feeling right now...
will get this sucker back together asap and wring its neck all day tomorrow...
thanks for the input Voodoo..
again what a dumba$$ i am
this i'm assuming is the reason WHY you shouldn't tow a jetski without clamping the water inlet from the pump..????

Yanno what.... I found all of these goofballs when I did the EXACT same thing as you. Googled and found the Riva forum, they saved my ski, then I followed the crowd over here. My ski survived just fine, seemed to run better actually. We called it the water treatment.

Get that ski back out on the water ASAP!!! Maybe add a little extra oil in the fuel for added lube. Try to run a full tank if possible.

Here's the latest news....
the engine has been pulled outta this ski...
the water was everywhere.. up in the power valves... EVERYWHERE..!!!
ALSO the rear oilseals were shot to sh!t...!!! the outer one was actually hanging out..???
which has been having a rare old time to itself, rubbing away at the drive coupler..(rubbing long time baby)
the inner one came out with a little push there is/was no spring ring on either of the seals..??
So opinions on this dilema.. TO recap:- an oil line was off,
thats the reason the head came off in the first place to check the jugs... NO DAMAGE..!! phew..
the ski couldn't burst 60mph.. would this be due to the rear oil seals leaking cranking compression..??
there was always a pong of fuel..!!
the front oil seal will be checked when the crank cases get split..!!
as well as anything else up in there..!!!
NOW would it be a good idea to get this crank trued/welded while the fecker is in bits..???
can any good crank shop do this..?? more importantly what exactly gets welded..?? pictures/links please gents..
apologies for the long post..
