    Good hack for a throttle lock on an older 15hp?

    I've got a late '70's 15hp motor on my sailboat and I recent got myself an auto tiller for the boat. This is a pretty cool device that will allow me to step away from tiller read a book, have some food, do whatever while the boat is under sail. What it could ALSO do is self steer when motor is...

    Telltale installation on a 1965 6hp - on exhaust housing?

    Hi, Yes, I know, there’s no need for this, lots of water comes out the exhaust which is clearly visible but, well I want a telltale anway. I’ve seen some videos suggesting installing a telltale right on top of the thermostat housing which I’m not a huge fan off - anyone see any concerns with...

    Johnson 1996 Triple 25hp - can I get better compression if…

    Working on this 25hp triple (1996). Actually, really no longer working on it because it’s now running fine. Compression is 110/110/115 which I find to be on the low side of acceptable. There are signs the engine did overheat previously: whiteness / paint chipping at seam of head and block. If...

    Johnson 6hp 1962 - Replaced prop shaft seal and now it’s popping out

    Trying to do a good deed for my nephew: his gearcase had a bit of water in it. Got all the parts cleaned and replacement parts put in. When I put the prop shaft seal back into the gearcase head/bearing it went it more easily than I expected. I checked the dia against the old seal and they were...

    1998 25hp Triple - not running past 2000rpm

    I’m working on a 25hp 3cyl 1998. I got this thing only so that I could swap the lower unit with my 35 because I need the 35 to now be a long shaft. Well, nothing is that simple. The 25 I want to sell won’t fully rev. Having experienced this before with my 35, it seems to have put itself in SLOW...

    Is my lower unit causing my bogging issues?

    so here what I’m up against: 1987 20hp Evinrude. Carb thoroughly cleaned 2x in bath of varsol over 48hrs, new carb kit put in, plugs, sub’d in another coil and tried in cyl 1 and cyl 2, new fuel lines, replacement fuel pump, replacement CDI, new lower crank seal, new intake and reed gaskets and...

    Can wrong plugs and large gap cause bogging…?

    Went out on the water last night to test an engine and had some issues. Engine started beautifully and idles nicely but taking it past 1/3 throttle was a bit of an adventure. At first it might be fine but then power would go down to almost idle then maybe come back up but then come right back...

    Fuel pump brass fitting on output side

    I’m chasing down a bogging down at higher speed that can be solved by pumping the priming hose. All seems to be in order but I do wonder about the change in hose size coming out of the fuel pump. The orifice at the bottom is a larger one (same as for hose from tank hose to fuel pump) and then...

    80/90 compression on a 73 15hp

    Hi Gang, I think I know the answer to this but wanted to ask anyway. I took the boat out of for a spin on Sat evening. Thing ran great for about 15min but then it started to miss regularly. That lasted for about 5-10min (misses every few seconds). Then it stopped fluttering and was clearly...

    OK feeling a little foolish…spark, compression, starter fluid no reaction…

    Alright…bit embarrassed to be asking this one but I’m stumped: 15hp 2 stroke ’73 with points 1) checked compression: 115psi in each cylinder (‘early 70’s 15hp Evinrude with points) 2) verified spark it jumps a nice thick gap 3) gave it a little shot of carb cleaner in each cylinder after having...

    Upper mounts on 20hp 1985 - different for short and long shaft???

    Hi, Marineengine lists two different upper mounts for long and short shaft for this vintage. Unfortunately, the one listed for s/s are $109 each with the longshaft ones being $40… Why are the two different and what exactly are the differences, do any of you know? The two bits are parts 325974...

    Looking for a CDI Unit for a 1991 DT15C outboard (2 stroke, 15hp)

    Hi, this damned motor has been sitting on my rack for 5 months now and nothing has come up on eBay as far as replacement parts. Lots of parts coming up for the plain old DT15 but the CDI unit for the “C” is different. Anyhow, if anyone had one, I’m very interested!

    Installing a kill switch on a 15hp 1984 2 stroke

    Hey gang, EDIT: got my motors mixed up - this is for a 1993 30hp, not the 15 as per title! I got a replacement CDI for this motor and installed it over the weekend. I’m in the process of re-installing a kill switch but can’t seem to find any wire I can plug the kill switch into. I THINK all I...

    1978 15hp - will I get an exhaust leak if back corner bolt is stripped?

    Thinking I’m probably ok…opinions? I only discovered this after putting everything back together so not really keen on pulling head again unless I have to…

    Compression on a 25hp Triple 1998 2 stroke

    I’ve got two of these motors. The first gas compression at 135psi. The second motor has 125psi across all thre cylinders. Im thinking that number is still fine. Do any of you disagree?

    Looking for a CDI for a DT15C motor if anyone has got a spare

    Hi, As the title says, I'm in search of a CDI unit for my 1990 DT15C. If any of you have got a spare that you are willing to sell let me know. The motor I've got is in great shape (mechanically anyway) but can't seem to locate a CDI to get it back on the water.

    What happened? Evinrude 35hp 2-stroke overheated?

    Strange thing happened to us over the weekend. Took the boat out for a spin. Took it out for about 20min in some moderate Lake Ontario waves without issue. Docked in for a few hours and then went back out. Waves were once again moderate but prop wasn’t coming out of water except on very few...

    Troubleshooting no spark On DT15C

    No spark condition on this bad boy. Finally got my hands on a service manual. The stator primary coil tests fine, But one of the leads on the pulser coil leads tests out of range. I will be honest I’m not totally understanding how the pulser coil works. If I understand it correctly, if one of...

    Parts diagrams for DT15C 1990?

    Hi gang, Struggling to work through a no-spark issue on this outboard I’ve purchased. It’s possible I have a bad stator (two of four wires have a reading to ground). I should have a service manual in hand later this week so will be able to confirm. In the meantime, trying to figure out how...

    Timing Setting at Idle DT15V 15hp 2 stroke 1991?

    Hi, I picked one of these up yesterday. Owner said it ran fine until he messed with the idle timing adjustment. Anyone happen to know what the timing should be at idle and WOT? I’ve got an owner’s manual headed my way but I’m impatient to start my troubleshooting. Thanks
