    Potential buy "Single inline 6 cyl mercruiser motor" unknown year

    Hello I/O geniuses! I'm going to look at a boat later today that has a "Single inline 6 cyl mercruiser motor" with a "newer outdrive" and I'm looking for some tips/advice. The guy says it will crank but needs some carb work. I know that more information would be very helpful here, but I...

    1996 FORCE 120 > Tilt and Trim not working

    Hi, I'm looking at a 1996 Force 120 with a couple of problems. The one I'm working on first is the tilt and trim because I understand that it might take a lot of $$$ to fix if it's truly broken... so the other problem may be moot if the tilt/trim is busted. The tilt/trim motor runs fine, it's...

    stator tests bad > Will engine still run?

    What's up boat gurus? Sorry for the generic question, but I'm curious to know exactly what the stator does. I know it's involved in sending the charge to the power pack. Here's my specific question... I have a 3 cyl motor (1984 Johnson 70hp) and my stator tested bad on one lead (resistance...

    84 Johnson 70hp > Suddenly Died > Recently replaced key switch

    What's up, my boat motor geniuses? Replaced key switch over winter after boat wouldn't start at the midway point of my one trip to get oysters, sub 40 degrees in October with no tow insurance. 60 degrees here last Saturday so I took the wife and 2 year old out. Successful trip, but boat died...

    Installing Replacement Key Switch

    I have a 6 post key switch with push-in choke that I suspect to be bad so I'm replacing it. The new key switch I have on hand is also a 6 post with push-in choke but the posts are labeled differently on the new switch so I want to make sure that I install it correctly. The old switch had these...

    1984 Johnson 70 - No Spark

    Starter engages, but no spark. Motor did something that didn't sound right at the exact moment that I turned the key off last (can't say for sure, but I think it originated from the key/ignition switch). Is there any chance a wiring problem in the console could be the culprit? + No spark at...

    Figuring out Model # of potential parts motor

    There's a guy in town that's selling an "early 80s Johnson 70hp Seahorse" that I'm considering as a back up/parts motor for my 1984 70hp Johnson. He says he can't find the plate that contains the model number but has supplied two numbers from above the cylinders. Is it possible to get the...

    Can you recommend a fuse for my homemade flounder light?

    I've got a theoretically water tight flounder light that I made. Although the plans I used don't include one, I'm thinking that putting in a simple fuse would be the prudent thing to do. Can anybody tell me what kind of fuse I need? The light is 55 watts I believe and it's running off of a...

    1984 Johnson 70hp - Poor Idle

    I'll try to keep it short... Old problem: Ran fine at idle and on muffs, bogged under load. Replaced fuel line, cleaned high speed jets (high speed jets only, did not remove and rebuild whole carb). After: Ran fine for an entire trip (2 hours). New problem: Took the boat out for a 2nd trip...

    1985 Johnson 70hp - Carb Adjustment and Service Manual Questions

    1) I'm going to follow the iboats #1 most recommended thing to do first: get the service manual. Question is, what exactly do I need? The "Service Manual Set?" Does anyone with experience know if manual 507508 is the right one for me to get? This is a 1985 Johnson 70hp WITHOUT VRO (not sure...

    Honda BF20 Can't Get Out of Gear After Replacing Impeller

    2003 Honda 20hp SHA So after replacing the impeller kit and putting the lower unit back on, I can't get it out of gear. It's stuck in forward. With the Lower Unit installed, the prop turns when the motor turns, but it won't shift out of gear. When I take off the lower unit the prop spins...

    1985 Johnson 70 Won't Shift Into Gear

    I bought this engine with a boat recently and the seller had it professionally maintained whenever something went wrong. He says it went into gear the last time he took it out over a year ago. He claims to have started it regularly over the past year (and I believe him) but never tried...

    Mid 80s 70hp Cylinder Compression

    Hi all, I'm thinking of buying my first boat and I need some motor advice. I've been told that one of the most important factors is the condition of the motor. That being said, the seller initially said the compression was good on this older 70hp Johnson (I'm guessing early to mid 80s by the...

    Hi All, Motor was running well cruising at about 80% throttle when suddenly it was as if I slowly throttled down to 25%. I took it down to idle and tried to throttle back up just to see what it would do. It didn't do anything and it died seconds later with two squeeks with the last two turns...
