Have Boat Questions? Ask a Boat Repair Expert.
Hello. My name is Tan.
Could I get the make, model and serial number of your engine please.
Is the trim pump in the boat or on the engine? You are right in the model year it changed from inside boat to engine?
Does the trim motor run? In either direction?
Ok since the oil is milky we need to change the oil this may make it work correctly. Remove the pump from bracket and turn pump upside down draining the oil. Drain as much out as possible. Then fill up. Disconnect one of the oil lines and run as much oil out as you can. Then refill with oil again. Continue this process till oil become clear again. Then reconnect the oil line and see if the trim will function correctly. Use 30 weight motor oil.
What happens is the water is so high on the back of the motor it will suffocate the motor due to be so deep in the water. Try tilting the motor up so it sits higher in the water.
Is it ok once the boat is in the water?
Yes you have to tilt the engine up so it isn't drowning out.
Yes 2 strokes are bad about back pressure in the exhaust. This cause the engine to die from not good exhaust air flow. It's like blocking the exhaust pipe on your car. It will die from to much exhaust back pressure. Tilting the engine relieves the back pressure letting engine idle better.
The hydraulic system is a sealed system. The only way water can get in the oil is through the reservoir. If the rams were leaking it would be leaking fluid around the rams. The only other way is through a bad trim line there again it would be leaking out there also. So the only real place is from the reservoir. The dipstick has an o-ring is it in good condition? Was the dipstick in the reservoir tight?
I don't see an o-ring on the dip stick this will allow water in the reservoir.
Yeah the o-ring on the dipstick is missing. Who knows how long.
It's going to take quite a bit of oil to get it cleaned out.
Yes it will as there is weight on the rams.
