    84 Evinrude 70hp surging

    Motor is surging above 4K rpm. I have cleaned the carbs, tightened all fuel fittings, replaced tank with known good tank, inspected fuel pump screen filter and diaphram and made sure of fresh fuel. Spark test under load shows good spark, compression is even at 100# in all three, choking does not...

    70hp Evinrude powerhead questioin

    I've got a 1984 Evinrude 70hp with a tired powerhead. Compression, while even is only 95-100psi on all three cylinders after a good decarb. I have found a donor powerhead locally but it is a 1989 model powerhead. Will this work as a direct replacement?

    Patching aluminum corrosion

    I have some corrosion that has formed on the bottom of my aluminum hulled 16' boat. It has began pitting the aluminum enough to where it needs to be filled. Oddly enough, these areas are right where the rear bunks support the hull. I use it in mainly fresh water, but I sometimes use it in...

    Smart Tabs for a flats boat?

    I have a 16? flatbottom boat with floatation pods and a box tunnel for running flats and shallow water. My problem is that the tunnel creates a terrible vacuum that sucks the stern of the boat down, reducing my speed by almost 25% and severely lugging(3500-4000RPM) the 70HP 2 stroke I have on...

    Hot battery terminals

    1989 Mercruiser 3.0L After charging my starting battery, I tried to crank the engine and it starts the first time. I then shut it down and try to restart and the starter slows down dramatically and fails to crank the engine. The + and - wires to the battery, to the starter and main ground...

    Valve adjustments?

    I finally found some time to get the boat put back together last night after repllacing the blown head gasket(1989 Mercrusier 3.0L). I adjusted the valves by finding TDC for each cylinder, removing all lash and tightening down one full turn for both the intake and exhasut valves for that...

    Need part number for fuel line

    1989 3.0 L Aplha 1 Serial OC480704 I had a stuck fitting on the carb end of the fuel line (fuel pump to carb metal line) and kinked the line. I figured it was toast anyway so I twisted it off. Now I need a new line and was hoping NAPA might have it. Does anyone have a Sierra part number they...

    Update : Forgot my plug....

    1989 3.0 Mercruiser I recently found out that my compression numbers were 75 psi and 50 psi in #1 and #2. I did a wet compression test and the compression only went up 10 psi in each cylinder (#1 and #2) so I pulled the head thinking the head gasket or valves. Sure enough, the head gasket...

    Forgot my plug and now motor won't start!

    I have a 1989 17' bowrider with 3.0 Mercruiser. I had my boat in the shop to replace a shift cable recently and when I took it out for a test run, I forgot to put the plug in. I tried to plane off and the bow went straight in the air and wouldn't plane and when it came down it sputtered and...

    3.0L Mercruiser petcock/drain locations

    I have an online subscription to Seloc but I can't find but one petcock location on the port side at the rear of the engine. With temps dipping below freezing the next few night here in NC, I need to at least drain the water from the engine and outdrive to avoid freeze up. Can anyone tell me...

    Mercruiser 3.0L tilt/trim not working

    I just bought a 1989 Winner Intrigue 17' bowrider wit 3.0L Mercruiser/Alpha 1 and I'm having trouble getting the tilt/trim to work. When I bought it, we had to take apart the trim motor and clean corrosion from the armature and wiggle the brushes to get it to work. We also blew out the...

    Dumb ? about motor mounting

    I am a novice at boating and I am having trouble with water spray traveling up my motor shaft and back into the transom. Is it possible to move the motor up on the transom so that the L-shape motor bracket no longer attaches to the transom. All that will be holding the motor to the transom is...

    Water pouring in over transom

    I have a 1648 CC Alweld aluminum tunnel hull boat with a 40 hp Mariner. The boat also has floatation pods welded on the back of the transom to aid in shallow water operation. <br /><br />Recently I have had troubles with water pouring in over the transom during operation requiring me to run...

    40 HP Mariner - could it be the power pack?

    My 1989 Mariner 40 HP is giving me some trouble. I did a compression check and they are 125, 125, 126, and 121 psi, so that seems to be fine. It starts and idles fine, but seems to be missing b/c it doesn't run as smoothly as it should at WOT. It seems to be a constant missing in the firing...
