    Mercruiser 165's First Engine Align, Having Trouble

    I think you have the rear mounts installed correctly. At this point I would go ahead and mount the drives. If any of the rear mounting hardware was not in place or wrongly installed you would be able to tell by comparing from port to starboard.

    Confused New Owner of an Old Boat

    Try to post a picture of the crack on the gear housing. IMP boats were well built as I had a customer who had one. This being a “sweet water” boat the engine and manifold might be good enough for the time being. Your main issues will be with the drive shift cable system and possible...

    How to Diagnose No Fuel at Carb 7.4

    When the engine was rebuilt did you install the fuel pump push rod that works the fuel pump?

    Mercruiser 165's First Engine Align, Having Trouble

    I had the mounts cut and re welded depending on how much “drop” I needed. Most times 1.5” worked out. Mercruiser did make a short mount but you will have to do some searching. I even kept a shortened one in stock.

    Confused New Owner of an Old Boat

    If the crack runs parallel to the prop shaft it would not be worth trying to repair it. Get a SEI unit and be finished with it.

    MerCruiser 5.0 Carb Engine Compression Test, Two Piston came back with Zero

    Whether it is a Ford or Chevy engine it probably has stuck valves, if so then either there are some bent push rods or just some of the rocker arm studs have been pulled up. No big deal hammering them back but you have to free up the stuck valves. If you can do that then squirt some Marvel...

    MC1 Gimble housing water tube smashed

    If you can get channelock pliers across and squeeze where the tube is kinked and then with a short 3/8’ drive extension in the tube while pulling you might be able to straighten it out enough. It does not have to be perfect.

    Outboard needed.. interchangeability

    All stern drives, mercruiser, Volvo and OMC after 1977 were 4” shorter there fore the engines sat lower in the boat. Stamas hulls were made pretty good and hold up well. If the stringers are still solid you could have the transom filled then have an outboard bracket mounted then a 150-200 hp...

    Carb Needle condition / function

    I bet that your fuel pump is not a genuine marine version. You should look into the correct pump for your engine. Does it have the Tygon hose from the side of the pump to the flame arrestor? Which engine do you have?

    Mercruiser 165's First Engine Align, Having Trouble

    A small bottle jack might work with some wood bridged across under the engines. I have worked on several 25s and I know they are a PITA to work on.

    Mercruiser 165's First Engine Align, Having Trouble

    I agree with the 2 fingers feel. I have seen myself beat the hell out of the alignment tool up/down/left/right and still not able to get it where I wanted it. As long as you do not have to “pile drive” the drive on it should be good. Usually as the boat gets a few hours everything falls into...

    Carb Needle condition / function

    Check that where the needles protrude into the throttle body that the holes are not raised from over tightening, with the screws out the bore must be smooth. If the area around the small holes are raised you will have a hard time getting the idle smooth. In other words, the throttle body is...

    Can I Tell if Water is Getting into the U-Joint Bellows?

    The hole can only be seen with the drive off or the engine removed. Was you able to install the bellows like I told you in the PM I sent?

    Can I Tell if Water is Getting into the U-Joint Bellows?

    There should be a vent hole at the top of the housing. That is where the water will start to appear.

    Low Voltage to the Ignition Switch

    Should not hurt, I forgot to tell you that before. It will be a good idea to have a fuse in the temporary circuit.

    Low Voltage to the Ignition Switch

    The wire to the ignition switch comes from the harness. Can you tell if the harness is a genuine Mercruiser part. Some boat builders use a cheaper version. Bayliner is a good example. I just helped someone with a non mercruiser harness. We had to run new oil, temperature and ignition feed...
