Hoping someone may have some thoughts as to what might be causing low water output from exhaust.
Background - will try to keep it short!
Mid august fresh water pump fail, replaced
Impeller pump was leaking around the same time so replaced with complete new one (it was sold with the boat) installed new seals and new impellor.
Water flow was good for a couple of weeks.
Now water output is much less and noticed the temp guage is higher than normal but acceptable but only after running 20 min at around 16-19rpms
Boat is hauling in a couple of weeks. Plan is to go through engine and to also have new injectors put in or clean the old ones (thoughts on which is better?)
One thought is the impellor pump that was sold with the boat was bad? It looked brand new. I had new seals put in it and after installed worked pretty good for a while.
Is there any other place I should check for some obstruction?
Any suggestions welcome.
