  If the ETB throttle plate does not move when you move the throttle flipper on your Polaris Boat, you should perform the ETB learning procedure process. Check all PPU and ETB wiring harnesses and connections. Connect digital Wrench software to the ECU, verify the ETB learning procedure displays “TRUE”, and ensure the ETB throttle plate is not obstructed by any foreign material.

Why is my Polaris msx 150 Boat engine losing power?
- E
  Elizabeth MooreAug 21, 2025
  If your Polaris boat engine loses power, several factors could be responsible. A weak spark might be the issue, so consider replacing the spark plugs and/or wires. Incorrect fuel or fuel mixture can also cause power loss; replace it with fresh, recommended fuel. If water is present in the fuel or oil reservoir, replace it with recommended fluids. A clogged jet pump intake can also lead to power loss, so clean the intake. For a clogged fuel filter, you may need to see your Polaris dealer or replace the filter. Clean the exhaust and flush the cooling system if they are clogged. If the issue is hydrolock or mechanical failure, it's best to consult your Polaris dealer. Also, ensure you are not overloading the craft beyond its specifications by reducing the load.

What to do if my Polaris msx 150 Boat engine doesn’t turn over?
- S
  smithjohnSep 7, 2025
  If your Polaris boat engine won't turn over, several issues could be the cause. It might be due to a blown fuse, in which case you should replace the fuse. Alternatively, the battery voltage could be low; recharge it to 12.8 VDC. Check for loose battery connections or ground and tighten them if needed. Also, ensure the lanyard lock plate is correctly installed under the shut-off switch. For hydrolock or loose starter relay connections, it's best to check all connections and tighten them.

  If your Polaris Boat engine turns over but doesn't start, it could be due to several reasons. First, check if you are out of fuel and refuel with fresh, recommended fuel. Old or non-recommended fuel can also be a culprit, so replace it with fresh, recommended fuel. Inspect the spark plugs for fouling or defects and replace them if needed. A clogged fuel filter could also be the problem; you may need to see your Polaris dealer or replace the filter. Also, ensure that the battery voltage is at 12.8 VDC by recharging it if necessary. For a crankcase filled with water or fuel or mechanical failure, it's best to see your Polaris dealer.
