Some concerns after winterization

Recommended Posts

Brantb

I hooked my boat up to a fake a lake today now that it is getting warmer to make sure all is good. I now have some concerns.

 

First, there is quite a bit of water coming from the shaft. Is this normal? From searching i think i have a dropless, which make me things there should only be a few drops.

 

Second is the water coming out of the exhaust isnt that hot. It is maybe luke warm, but the engine was up to operating temp. I pulled the plugs from the block and the water there is hot.

 

Is this normal after the everything being dry for 6 months?

normal and normal.  It takes a LONG time (if ever) for a boat to get truly HOT on the hose.

@shawndoggy thanks for the quick response. I was a little nervous. I was thinking that i would be having to call the dealer and i know they will be getting slammed soon.

Raw water is taken in and when it gets to the thermostat it is routed into 2 areas: engine cooling (based on need) and the rest to exhaust cooling.  Engine cooling water should never get above ~160 degrees, regardless of power setting as flow will go up via the thermostat to keep it at 160 degrees.  After the engine cooling water does its job it then goes to the exhaust manifold.  The excess water that is bypassed for engine cooing goes directly into the exhaust manifold for exhaust cooling.  So if you're only running the engine at idle, a majority of the cold water is going to the exhaust, which isn't going to get very hot due to the low power setting...and since you're only at idle the demand for cold water is low.  Even at idle the impeller is pushing a lot of cold water through the motor, so between the 2 water sources the water should be well below 160 degrees, even if the engine is fully up to temp.

FWIW, a "dripless" shaft seal means that no water drips into the boat.

With the dripless system, water is diverted [through a hose branching off the raw water circulation, just distal to the transmission cooler] to the dripless seal, where, under pressure, it is forced out through the hull around the drive shaft, providing a thin film of water to keep that drive shaft lubricated and cool while spinning however many revolutions per minute.

So, its perfectly normal for you to see that water dribbling out around the shaft while using the Fake-A-Lake.
