What specifically should I look for in the engine mountings? They don't seem deformed or broken. Thanks, Chris They should hold the motor more or less in the right place. If not torn or broken, they are likely up to spec. The right stiffness may make a difference to percieved vibration. Terry K |

What is air lock? Thanks, Chris Air lock can be different things, but occurs when air somehow stops a pump or drain. Air lock in a suction line may be simply an air leak in the line, or may be a partial vacuum in a sealed tank of fuel caused by not letting air get into the tank to relieve the vacuum. Air lock in a drain won't let water out of i.e. your toilet, when the drain vent, on the roof of your house, gets plugged with snow, ice, leaves or birds' nests. The overpressure in the drain line can impede the evacuation of the water. Vapour lock is when fuel in the fuel line boils and acts the same as if you had an air leak in the pump suction line, preventing a pump from reducing pressure in the intake line sufficiently for ambient atmospheric pressure to propel liquid to the pump.

Good evening, Chris,
Very unlikely that's a Johnson OUTBOARD part. There's a whole different Johnson company that manufactures a line of marine engine cooling pumps. Check out www.johnson-pump.com then "Google around" and find a dealer who discounts the service parts. Not West Marine/Boat US, BTW.

It has 'Johnson' imprinted on it. Are outboard parts cheaper? |

(*) This brings me to another question:
Where do I get cheaper Yanmar parts? I paid $36 for the impeller, that seems an awful lot of money for a tiny piece of rubber. It has 'Johnson' imprinted on it. Are outboard parts cheaper? The Johnson pumps are Swedish made pump. I have one on my Yanmar 3GM30 for the seawater pump. I don't know where you got your impeller, but I got two for that price last week. I think I ordered out of the Lewis Marine catalog at my local marina, where I had overnight delivery. Johnson part # 09-810B-1 Leanne s/v Fundy W1WXS |

Thanks for all the input! A hand rasp worked well, took off the required 1/2" in less than 15 minutes. Chris |
