    # of drain plugs

    I would normally just figure this out myself, but I have to take a quick run to the lake tonight to drain the boat block (going down to 27*), the manual is at the lake not at my house, and I don't want to make any mistakes. I have a 1989 Mercruiser, 4.3L, 202 CID, V6 engine with power steering...

    Fogging Oil

    I have a lake house where my boats are located and unfortunately I do not get down there as much as I like. Sometimes I can go a month in the summer without going down there. The question: is there any benefit to using fogging oil on the boats each time I pull them out at the end of the...

    Water exhaust port

    I have a 1989 Mercruiser, 4.3L, V6, 262 CID motor with an Alpha 1 outdrive. The question is where does the water exit the outdrive? I know that the exhaust is supposed to come out of the propeller, but does the water also come out there or up around the bell housing? My wife and I were...

    True Newbie Question

    I am going to remove my sterndrive to inspect the bellows and what not, however, how do I use the alignment tool to get the drive back on? It seems like everyone, including my manual, just assumes that you know how to use it, but my luck, I will screw something up. Thanks for the help!

    Belt Tension Procedure

    I have a 1989 4.3L V6 262 CID. Ok, I understand the deflection test to see if the belt tension is correct, but is there a better way. What I have been doing is laying a ruler between two pullyes on the same belt, applying pressure to the belt and so long as it does not deflect more than the...

    Trim Motor Double Check

    Ok, so the last time I went to pull my boat out of the water, I pushed the trailer button and the trim motor made a lovely grinding sound for about 10 seconds and then stopped. It has made this grinding sound before and has worked, so we figured it has worked again and the motor was up. We...

    Gear Shifting Problems

    So I finally got the boat out in the water and she was running great (even did well slowly towing someone for a half hour!!), but it was not all fun and games. When I got back to the dock, I shifted into neutral and then into reverse and it sounded like it did not shift well. This was...

    No power are full throttle

    I have an 89 Mercruiser I/O, 4.3L, Thunderbolt Ignition, 262 CID, 6 cylinder. I have recenlty rebuilt the carburtor, replaced the plugs, wires, and distributor. When I would start it at home on the muffs, it would start up, the idle is rough, but in throttle only it would run smooth and had...

    Fuel Line Question

    I recently installed my rebuilt carburetor and reattached all cables and the fuel line. It now appears that I need to remove the fuel line, however I am having a great amount of difficulity doing so. I am using one wrench to hold the fuel inlet nut and one wrench to turn the fuel line nut...

    Engine Tune Up Question

    Ok. I got the new distributor and PROPERLY tightened it this time. The spark plugs are all seated and tightened correctly and are attached to the correct wires. I can now start the boat, but after about 10 seconds it dies in idle. If I start in throttle only it starts up, runs a little...

    Distributor Mistake

    Ok, I replaced the spark plugs, wires, rotor and was reinstalling the cap when I tighetened one of the four screws too hard and cracked the plastic housing. This is a brand new cap, so I was wondering if there is any way to repair this? Can I just superglue the crack shut, can I put some black...

    Fuel Line Question

    I know this is a silly question to ask, but does anyone know the size of the fuel line from the feul tank to the feul pump on a Mercruiser 175HP 4.3L engine. Choices are 3/8" or 5/8". Thank you!

    Water in the Pontoons?

    I recently pulled my pontoon boat out of the water and noticed that there seems to be water inside the pontoons. We have owned this boat for approximately 13 years, and I am sure we have never drained the pontoons. There are drain plugs on the back of the pontoons, and I am wondering if I...

    Carb Rebuid Question

    I have taken the whole carburetor apart and I have a question. When I removed the acceleartor pump assembly, there was a spring below the accelerator pump but no retaining clip and no check ball. Since they were not there when I took it apart, should I put them back when I put it together...

    Carb Rebuild Problem

    I have reached a problem on my carb rebuild. The screw (phillips head) that holds the choke lever on has become stripped. I tried to use a dremel to cut a notch so that I could use a regular screwdriver and that only made it worse Now I have no leverage on the screw what so ever. Should i...
