We have just come into a new to us Trawler. We have typically been Sailboat creatures and are comfortable working on our Yanmars, Perkins and Kabotas...we now find ourselves with a beast of an entirely different color. We have spent several days trying to find information and assistance as we feel the engine is not performing as we would have expected.
The first thing that we found is the impeller was completely toast. The exhaust system had to be replaced. All of this has been done and there is water now gushing through the water-cooled exhaust.
What we do know:
This is a keel-cooled system
There is oil in it
It cranks up first time every time
It dies after we have run it for about 20 minutes
What we need to know
1. How do you check the coolant on a keel cooled system
2. How do you tell if your oil filter is clogged and needs replacingj
3. What should oil pressure be (ideally) at
idle:
Cruising (5 knots - sailboaters remember )
Full Throttle
4. What might cause smoke to come from the dip stick (not billowing like an explosion but noticeable to those looking)
5. Is there a strainer that is in the oil pan or is it somewhere easily accessible and should that be changed
6. What temp should the motor be expected to run at
7. What should the ideal RPMS be run at during cruising (vessel is 29 ft with 23 in 3 blade prop)
8. Can the motor be ran to fast or is there a governor
9. What type of mileage might we be able to expect traveling at approximately 5 to 6 knots
Thank you so very much for taking the time to answer any of the questions - we need all the help we can get!!
