    Fire onboard 76 Islander

    Yesterday turned ugly on the way home from fishing. First the wind picked up and we wound up fighting 35 to 45 mph winds and 2 to 3 foot rollers breaking. The rollers are not a concern since I have an Islander and it is a pretty deep hull and loves to plow through. I do only have the old 120 HP...

    Impeller Question

    I am getting ready to order an impeller kit for my 1976 Mercruiser 120 with what is apparently called the pre-alpha outdrive. Where can I find the model number for the outdrive? I found the serial number 4444943 but that isn't helping me a whole lot. I need a new impeller kit for the old girl...

    Trim Limit Switch Wires

    Is there a secret to running new trim limit switch wires without pulling pretty much the motor or the outdrive? I would rather not drill a new hole in the transom but not opposed to it either. Too crippled to be cramped up in the compartment for too long. If anyone has a secret please let me...

    So I am buying a 76 starcraft islander that has the 2.5 mercruiser or iron duke. it doesn't have a heat exchanger. I am buying it from a family who has owned it for the past 16 years and they said it hasn't had one since they bought it from the forest service. Did the 2.5 ever come with a...

    73 Johnson 65hp WOT sweet spot

    Can anyone tell me what the WOT RPM is for a 1973 Johnson 65Hp is? I try to keep it in the 4500 to 5K range but the whole speed thing isn't a major concern for me. I am quite happy chugging along but I can't remember what the max RPM is anymore. I have the factory manual but I moved a couple...

    Comprop likes/dislikes

    I have a 73 Johnson 65hp and I am in the market for another prop. Has anyone used a Comprop and what are your thoughts on it. I am pushing a 1973 Fiberform Columbia and I run about 200lbs of gear at any given time. I don't worry about rocks all that much since most of the mountain reservoirs...

    Coils question 73 Johnson

    I am testing my coils today and I am getting a good blue spark at half inch so I reinstalled the plugs and fired it up. I can pull the top plug wire off and there is very little change on the motor but you can tell the motor picks back up right as I reconnect the wire. If I pull the second...

    Johnny 65hp max rpm 3500

    Figured I would run something past you all before I tear into my carbs. My 1973 Johnny 65hp tops out at a whoppin 3500 rpm. I have OHM tested everything and so far all test good according to the factory manual. I just picked up a spark test tool and set it at .4375 and the spark jumped really...

    73 Johnson 65HP 3500 max RPM

    I have a 73 johnson 65hp that won't go over 3500 RPM. The stator tests good and the carbs just had a fresh rebuild. I just replaced the rectifier due to the insulation on one of the wires was getting pretty weathered. I know for sure it isn't the Tach or the Prop. I used to run 5K on the RPM...

    73 johnson 65 WOT issues

    My 1973 Johnson 65hp won't get up to the correct WOT RPM. All electronics are good. Stator, Timer Base, Coils, and Powerpack all test good and so does the tach. I have done just about all I can think of. I am getting spark (bright blue)to all cylinders and the carbs are the cleanest carbs I...

    Turningpoint Prop

    I have a 73 Johnson 65hp and I have been running 17 pitch Turningpoint on it for years without problems. I decided to get a 15 pitch Turningpoint for when we go tubing just to help with getting the boat moving. With the new 15 the boat struggles to get out of its own way with out a heavy load...

    1973 johnson loses power

    I have a 73 johnson 65 that will run fine for miles and then the power dies. Occasionally it will kick back in and go. I have had the carbs apart and cleaned them/installed new kits. I am currently waiting on a new rectifier due to the old one having a bad wire casing. The motor starts and...

    I took my boat out for the first time in two year yesterday. I did a full stringer transom repair. I also pulled the carbs and soaked them and did a good cleaning on them. Installed a new head gasket, thermostat and plugs. The boat was running great for the first couple hours. When it came...
