    1968 Evinrude Lightwin Cooling

    Hi, I have a 1968 3hp Lightwin. It's been a sweet motor and I really enjoy booting around in it. I was getting ready for the first trip of the summer and put the motor in my test tank... and it got super hot. I wish I had been watching it a little closer, but I'm pretty sure it's okay: no...

    SportJet 175 XR2 Stalling under Constant Load

    Interesting. You mean this one right? My understanding is this one only runs when the starter is engaged. Can it somehow become a restriction or something? Or maybe you mean this one? It is a bit of a mystery to me....

    SportJet 175 XR2 Stalling under Constant Load

    Hi: I have a new to me SportJet 175 XR2. This engine was quicksilver remanufactured and professionally installed a few years ago. This was all done by the previous owner. He had blown the old engine in a unfortunate oil spilling event that led the engine to running out of oil. The old owner...

    Replacing Drain Tube (Bulkhead)

    Hi. So I'm looking at these drain tubes in my transom. I want to replace them both because they were definitely leaking into the transom. I'm not sure what they are called. The one for the splashwell (top) is this cheesy plastic thing and looks easy enough to replace and seal. But the bottom one...

    Methanol to Aid in Drying a Transom

    Hi: I have a rotten transom that I have decided to treat with hardener in an attempt to add strength. On researching this topic, it appears this type of repair can have varying levels of success. It does seem however, the chances of success are greatly increased if the transom can be dried out...

    Transom Void

    Hi: Here is the backstory on this one: On my early 70's GT150 knockoff, the transom has had a lot of flex in it and started to crack really bad right near the fibreglass transom cap that the engine rests on; right in the corner of the splashwell. I suspected a rotten transom so I cut that...

    Pourable Transom in Canada

    Hi: I have an early 70's GT150 knockoff, and I want to replace the transom. Since I have zero fibreglass experience, I am looking to try a pourable transom product. I've done a fair bit of looking around and have found a few products: SeaCast Arjay 6011 CarbonBond Ceramic Pour All of the...

    ~73 Mercury Suddenly 850 losses RPM After a Period of Time

    Hi: I have an old Mercury 850 from about 1973. It ran great for about an hour. Then it started... It would come out of the hole great and run great for a hundred yards or so, then would suddenly bog and lose RPM. Maybe losing a cylinder? I'm no expert but that's what it felt like. Funny thing...

    Steering Offset? Added CMC Tilt/Trim to 73 Johnson 135hp

    Hi. Over the winter I picked a used CMC Tilt/Trim assembly and installed it on my boat with a 73 Johnson 135hp. This unit works totally good and I'm very happy with it. But.... The tilt/trim unit creates a 5 or so inch engine setback when installed. This setback really screws with the geometry...

    Spaghetti Seal Alternative?

    Hi. I was surprised that I could not find a thread on this topic. For sure it's been done before, or maybe I'm crazy for thinking it. So I'm looking at reassembling my crankcase halves and realizing I have no 'spaghetti seal'... but I do have an oring making kit. Has anyone ever tried using...

    1973 Johnson Rebuild. Crankshaft Bearing Oiler?

    Hi. This thread is a continuation from my originally posted thread '1973 Johnson 135hp Ignition / Tachometer Issues'. Basically, an issue I had with my tachometer evolved into an engine rebuild - rings, and 1 piston. Attached are pictures of the upper crankcase. I mistook the 'oil plug' (whose...

    1973 Johnson 135hp Ignition / Tachometer Issues

    Northern Alberta. I think Mott's Machining in Edmonton would do it. I've been up all night thinking about my options, no sleep. Another long story short, I do have a 74' Johnson 115hp as well sitting on a stand. Thing is that one also it's share of problems. It has good compression, but I know...

    1973 Johnson 135hp Ignition / Tachometer Issues

    Hi: I am new to boats and outboard motors. I remember boating and skiing with my dad back in the day and I always thought boats were super cool. I don't know why it took me so long to get one of my own and go with my kids. In my mind they stopped making awesome boats in the 90's (not long after...
