    choosing a lower unit

    Which do you need? One is a drive the other is the lower half. If you get the whole drive you need to get the right ratio. If you get just the lower you only need to make sure it is NOT the one for a 2 or 2.4 ratio.

    EFI throttle body whine

    My throttle body has always had a high pitch whine coming from it at idle. When I first got it I thought it was just the nature of the EFI. I looked into it last year and thought it might be the high pressure fuel pump but that is not it and it is defiantly coming from the throttle body area...

    Why use diesel engine oil.

    So lets not turn this into an "oil thread". I know some people use engine oil normally meant for diesel engines in a gasoline engine. What is the thinking behind it? My only guess is because of the constant speeds and high loads. I am not looking for suggestions on brand or weight just...

    My turn to do it. Clean bilge and test pump.

    So I dropped the boat in today and after getting the trailer in I remember seeing the plug on the shelf in the garage. I asked my wife if the plug was in. She says "there's water coming out the side" (bilge pump outlet). I run back to the Burb and yank it out. We had a storm come through a...

    I found a good deal on plug wires for a 350 Mag of the same year as my EFI 5.7l motor. Will they work?

    5.7l EFI with cool fuel and fuel in the sight tube?

    Today we were out and just siting about 12 miles out from the launch. When we went to move the motor didn't want to start so I checked it out. There was fuel in the sight tube. I disconnected it from the flame arrestor to get it started and we high tailed it back to the launch. The sight...

    Cleaning brake line internals?

    When I go my trailer the brakes weren't working. The previous owner only used the trailer to launch and retrieve once a year so he didn't fix it. I decided to replace the actuator and have new drum brake plates that are complete units. Before I hook everything up I would like to clean out the...

    Mercruiser engine driven seawater pump compatibility.

    The original seawater pump on my boat was the multi piece housing type and has been converted to the one piece plastic type. I am looking to get an extra impeller to carry on board in case. Are the impellers between the two the same?

    Bravo installation kit. Which o-rings where?

    Re: Bravo installation kit. Which o-rings where? Thanks. What about the one around the shift linkage? Is that not part of the kit? I thought the water passage was sealed by the rectangle with the swoop in it.

    Boating handgun carry laws

    Re: Boating hangun carry laws Re: Boating hangun carry laws Spokane is the second largest city in Washington state behind Seattle. It is far from podunk. We are still not allowed to own SBRs or AOWs. We just got the right to own suppressors. My friend can own and manufacture or modify...

    1972 Mercury 75 (7.5hp) throttle/timing advance adjustment.

    I have a friend with the 1972 Mercury 75 7.5hp with some issues. He said it would start but then start "popping" and die. I am taking a look at it and found that when using the handle throttle the timing is advanced but the ramp that is supposed to move the throttle on the carb doesn't contact...

    I am looking for a hitch for our 2003 Suburban and found someone on Craigslist with a 2005 Yukon Denali factory hitch made by Northern Stamping. Does Anyone know if these are compatible? I can't seem to find much info on that brand.
