93 Mariner V135 - water from tell tale hole

[Tarheel Traveler]

Water not a stream from hole, have replaced water pump assy, water is not a steady stream, it comes out in spurts, while in water. On land with muffs on it is only a dribble. What is the next step to take? Only had boat about 2 months. Any info is appreciated.

Welcome to iboats and wait until it warms-up. Once the thermostat opens, it should have a good strong stream. Until then, it'll just dribble.

hello<br /> yep. replace the t-stats with the vented self flushing ones for an omc. they work better than the merc design. also clean the pressure relief valve and replace the diaphram.<br /> good luck and keep posting

I think rodbolt is right on track. Often you won't get a good flow out of the tell tale when on muffs especially at idle revs as most of the water is lost down the exhausts. The poppet valve is a prime cause of weak tell tale if the rest of the water pump has been replace. It is probably by-passing so much water out of the exhaust that there is not enough head left to make the tell tale.If it has never been changed I would be pretty sure that a new poppet assembly will go a long way to fluid utopia.
