    fs 81 sportfire with 86 xr2 150

    I understand not selling just the motor. I would buy the whole thing and deal with selling the boat myself.

    Sorry for the short message above. I am interested if the motor meets my needs. I am in Michigan (Lansing area) so I could come see it easy enough. Let me know.

    fs 81 sportfire with 86 xr2 150

    checkmate150 Is the motor oil injected? and is the oil tank mounted in the boat? I would like to maybe swap motors with my 81 Diplomat because I need a bow rider. Anymore info on the motor would be appreciated. Thanks

    Coop needs some help on an outboard.

    Some possible help I have a 1981 V6 150 that I'm sure is like yours. My serial # is on a plate that is below the cowling on the long casting that goes down to the lower unit. It is on the right side viewed from the motor front. It is possible the metal tag has been torn off I guess. My motor...

    Premix ratio

    Someone may want to go back to school for math. If you only mix 12 ounces in 10 gal of gas you will be running almost 100:1! Sounds like a good way to wreck your engine to me. This equates to about 4.8 gal of gas for 12 oz. of oil.

    rectifier/stator problem

    My 1981 Merc 150 has an ignition problem under load. Switch boxes have been changed with no change in performance. The stator reads voltage out of range while running, until the rectifier is disconnected. Can the rectifier pull down the stator output so much that it has weak spark? I'm not...

    No power

    I have a 1981 Merc 150 V6 that idle's OK, seems to have spark to all cylinders at idle and at 1000 rpm, but has so power to get the boat on plane. I first suspected I had water in the gas, so I changed the filter and made sure I had good gas, put new plugs in, but still no power. Has anyone...

    100:1 AMSOIL for outboards

    Has anyone used the AMSoil Saber 100:1 synthetic premix in their outboard? I would like to minimize the smoke from my 81 Merc 150 and want to try different oils than the Merc oil. This 100:1 caught my eye so I thought I would ask before I try and blow my motor! 100:1 seems awful lean to me.

    Stereo Setup

    Double battery wiring I can tell you how to wire the double battery. It is recommended that you use a battery switch so that you can use #1, #2, both, or none. I would post a picture if I could do attachments, but I think the system will not let me do now. If you send your e-mail I can send...
