    1965 6hp CDL-22 - no telltale with thermostat installed

    OK this one has got me stumped. I replaced the water pump with new t-stat and related gaskets last year, it ran great for summer and fall months. Started it up this year to find my new powerhead gasket leaking water in the front center, maybe I didn't torque it down enough or didn't use gasket...

    Sealing Livewell Hole Under Water Line

    Hello, I just purchased a 1986 grumman, and have been poking and prodding at it in my driveway. I found what seems to be a livewell opening with plastic fittings, plugged with a steel cap. It looked dubious so I figured I'd give it a yank to ensure it was on there good, and of course it just...

    1969 Alumnacraft Interior Build

    Hi, I've been following a few rebuilds and reading up on glass and these forums have been incredibly informative! Here's my position: I made a casting deck, removable floor, and seating for my tinny about two years ago, and I thought two coats of porch paint on the plywood would hold up for a...

    1973 Evinrude 25hp - Shifting Issues

    Hello, I've got a 1973 25hp that started developing a shifting issue (manual, no remote controls). It wasn't banging in and out of gear, but rather slipping into neutral at WOT. It would over-rev and obviously be in neutral, but the roller was not in the indentation in the arm below the pan...

    Water Under Gel Coat?

    1985 Checkmate - it's got some scratches and spider cracks, but not too bad looking from far away. This blister-thing appeared over the summer near the gas cap, and water seems to seep underneath the outer coating; I can push it around. It disappears when it dries out and comes back in the rain...

    Propping 18' Checkmate with Tower

    I've got a 1979 Merc 115 (inline) on the back of an 18' 1985 Checkmate bow rider... this was the first year Merc rated HP at the prop. Power trim and jack plate. Running a 19 pitch SS prop it came with. WOT operating range for the motor is 5000k-5500k I'm getting 5100k, reaching 48mph on GPS...

    Bracket Failure at WOT

    Still trying to figure out the cause (I'm still new to boating). This is the first season I was able to take out my boat - 1978 inline 1400 on a CMC jack plate - the thumbscrews for the transom clamp don't match up with the jack plate nicely (they wind up resting on the tops of CMC bolts), so...

    Can I convert my 1973 Mercury 1500 to distributorless?

    Re: Can I convert my 1973 Mercury 1500 to distributorless? Tell me I have a 115hp powerhead :facepalm: That would explain my lower-than-expected speed on the water. I guess it's a 1979 115 on a 1978 140 mid, that would make sense, sorry bout that, and thanks for telling me where to look!

    Rewire Project

    The wiring on this boat (18' checkmate) was a mess - nothing was fused, everything spliced into the panel with electric tape, and the battery had giant stacks of ring terminals - it was tough to get the wing nut on the battery even. After my lights shorted out on the water one night, I made it a...

    Stereo Upgrade Help

    1985 Checkmate 18' bow rider - the custom stereo system it came with sounded pretty awful and drained the battery fast... I don't know all too much about stereos but it looked sweet when I bought the boat :) Pulled some stuff apart and I think the speakers are cheapo and amp seems a bit funky...

    Propping a 140 Merc on Checkmate

    Finally got the trim working properly late in the season and I'm trying to find the correct prop size. I also tried to learn how to drive it properly in that short time, so I probably don't have everything optimally set up, but it would be great to get the jack plate at an optimal height and try...

    1978 1400 tower bogs in gear (video)

    Thought I got this "new to me" setup running good - new rectifier, new plugs, carbs rebuilt, water pump kit, LU oil, idles at 800 neutral, new fuel lines and bulb. It throttles up fine in neutral. I put it in the water for the first time and it bogs/dies near half-throttle. I checked spark with...

    1978 1400 tower - fuel line diameter

    Hi - trying to fix up this inline six, still a bit green at this so I've been going slow. I replaced the old bulb/fuel lines with the same diameter hose that was originally running from the tank, which was 1/4", but I've been seeing a few mentions of running 5/16" or even 3/4" all the way to...

    1953 15hp Drive Shaft Snapped - Investigation

    Re: 1953 15hp Drive Shaft Snapped - Investigation Sounds like a good possibility. Hm, I guess I have a drive pin? (didn't know there was a difference until now) - it sits back on the prop shaft, close to the seal, then a cotter pin holds the nut on. Perhaps it was supposed to break but...

    1953 15hp Drive Shaft Snapped - Investigation

    Here's the story: I picked up a non-running 15012 15 hp and wanted to restore it. I manage to get it running with the help of a donor motor, serial plate was also 15012 -from this I used mainly the flywheel, high speed needle, exhaust leg (the one I had was cracked), gear case, and other small...

    1955 7.5 drive shaft spring thing

    1955 7.5 Evinrude - didn't expect this spring mechanism at the powerhead-driveshaft connection. It kinda came apart before I could see what order all the parts were assembled... was wondering if anyone had a diagram handy?

    Inspecting Pressure Tank

    Been waiting to come across a cheap pressure tank to see if my 53 rude will even start up, but I'm getting impatient... found one for $60 local and I'd be willing to take a look. I've never really seen/inspected one in person - what problems or tell tale signs of a bad tank can I look for when...

    Identify fish carcass

    I didn't catch it, just found it washed up on the shores of NYC... never seen teeth like this before. Any ideas?

    Picked up a 1948 Elgin 5.5

    Model no. 571.58621 My second outboard, first "antique" - excited to try and get this running again. Having only a forward gear sounds pretty interesting! Supposedly it was sitting in a dry basement for the last 30 years... it looks pretty intact to me except for a knob and a spark plug boot...

    Wiring Diagram Advice for Small Boat

    Kind of new to wiring... I've always just hooked the wires onto the battery when I needed something when boating as a kid- didn't know about breakers, load, etc. Now I have my own boat and I'm trying to educate myself. I've read some posts on here and came up with a diagram for a small aluminum...
