    1980 Merc 115 hp

    Got a question here guys. I've acquired a boat that has a 1980 115hp merc on it and I'm not getting any fire to the plugs. I've switched power packs with 2 that I've had that I know are good. I've also disconnected the kill wires (black w/ yellow stripe) on the power packs to eliminate any...

    60 hp getting hot

    I'm helping my grandfather work on his 1984 60hp evinrude. He's having an issue with it getting hot and the overheat alarm sounding. I helped him put a new water pump in it and it's installed right. We changed the thermostat and poppet valve also. It's still getting hot though. We took the...

    88 SPL question

    Alright, got a question. I have a 96 88 SPL that I'm thinking the port side thermostat is stuck open. I had the motor on muffs today and got to feeling the heads. The port side is running a lot cooler to touch than the left so I went and got a digital thermometer and the port side is running...

    1983 75hp Evinrude

    The motor is mounted on a 17'6 bay boat. Here's my question, I don't think the tach is working correct. To me, it's reading higher than it should be. I have a 16P prop on it right now. If I go WOT, the RPM's go to 7k but at idle it's right at 850 RPM. I haven't kept it at the RPM range but...

    70hp issues

    I've got a 1978 johnson 70hp that is giving me issues. First off, the electronics have been converted to the newer style power pack instead of the old power pack with all the screws. Anyways, the boat has been running good until this morning. I was trying to get the tach hooked up and it was...

    fast track tilt/trim

    I've got a perfectly good working fast track unit laying around my house. My question is can I adapt it to work on my motor? My original tilt/trim is removed b/c I couldn't find any parts. To me it looks like the only issue would be that I'd need to change the 2 brackets that bolt the motor...

    Outboard Height

    I've got a twin vee that I'm repowering. My question is how high should I set the motor up for this hull? I've got it on the transom and the bottom bolts at the top of the slots. Here's a picture of what I'm working with. I guess what I'm asking is should the cavitation plate be even with...

    Wiring external overheat buzzer

    Anybody have any advice on how to do this? I'm more after what size of buzzer (watts, amps, ect..) My boat doesn't have one and I'm wanting to add it. The wiring is there but no buzzer. It's not the controls that have them built in.

    75 ski barge

    Alright, picked up this 75 ski barge for next to nothing and put my 85 horse on it and now I've got issues. First off, the motor on it was a short shaft and my motor is a long shaft so I had to build the bracket you see in the pics to raise my motor. Could have gotten a jack plate but did this...

    1970 johnson

    Picked up a boat with a 60 hp johnson. Serial number j3302419. Did a compression test. 125 psi on all 3 cylinders. Cleaned the carbs. Here's my deal, it has no spark. Is this motor worth the trouble to put more money into it? It might not have any spark b/c I don't have a for the control...

    79 lower unit stuck

    I can't for the life of me get the lower unit off to change the impeller. It's not the bolts that is holding it together. I've got them all out except for the 2 nuts on the side which need the unit to separate to remove them. It' acting like it's bound up toward those 2 nuts. The back is...

    Alright, since my other boat is up and running I figured I'd turn my attention to my bay boat. My OMC 140hp died a while back and I decided to trade it for a 79 140hp merc. I finally mounted it last night and started my wiring harness but have run into issues. I'm using quicksilver controls...

    78 Evinrude Problem

    Alright, so my journey begins again. This motor has run good up until last weekend. I get it out and am getting it ready to go to the lake and the motor won't start. For some odd reason when it decides it wants to spark it will. It's off and on with the spark. When it is firing it tries to...
