    Mercury 850 85hp. Good engine or stay away?

    I suppose the wires to helm are fine? Not sure how to really inspect them seeing as they're kinda sealed in that jacket? After looking at the engine side harness I probed alittle further down the harness towards the cowl and im not sure theres any really "good" wire left to splice to. Its...

    Mercury 850 85hp. Good engine or stay away?

    I haven't inspected the wires up to the helm yet. It sounds like I should re-wire it vs just seal it and let it ride. And yeah everything wire wise on the distributor side looked fine. And this is on a 1974 Caravelle Tarpon model. Alittle over a 15ft boat.

    Mercury 850 85hp. Good engine or stay away?

    It's definitely failing. And fallen off wires. And yeah I noticed it looked pretty straight forward to make the wiring for it if I wanted. Id love to keep it with the boat being original, if I can get it reliable.

    Mercury 850 85hp. Good engine or stay away?

    Well I went ahead and bought the boat. It's basically brand new I'm the second owner and he said the boats maybe been to the lake 10 times it's whole life otherwise it's been garaged. I'll check for spark before I bought it had good strong spark on all four. Brought it home hooked some fuel to...

    Mercury 850 85hp. Good engine or stay away?

    Looking at an older caravelle bow rider in beautiful shape. Boat is a 1974 model. I assume but haven't confirmed if the mercury is. If it's the older distributor setup should I stay away from it? Guy says it's been garage kept and hasn't ran in awhile.

    Fixed the idle issue. Long story short a piece of the old gasket was missing and I assumed nothing was missing when I copied it. Caused the idle circuit not to be able to draw fuel up correctly. I tossed in the sierra bowl gasket . The seal around the main "venturi" and the bowl and the...

    From what I can tell 1956 was the only model year for a 15hp in the 50s and 60s and a 15hp didn't return to the Johnson lineup till 74. At least that's what I can tell from sites showing s 15hp in 56 then a gap till 74. I'm sticking with 24:1 for now.

    So I found out going through the carb the low speed needle tip was bent right at the tip. I noticed before it had a tendency to "lean sneeze" or pop back when idled down and it didn't seem like adjusting the low speed did much at all. And there was no seal/packing in there like there is on the...

    The boats a 14ft crosby sea sled that's had a hard life. I had the boat for a bit and sold it. It resurfaced on marketplace and i got it back cheap. But it now has roll on bed liner on the hull. The rubbery kind. So im sure thats hurting things. Boats rated at 40hp and before the hull got...

    Yeah that line checked out good. Yes and no. I did order a kit and pump through Amazon. However. I also ordered a Sierra kit for the carb. The Sierra kit is supposed to be here in the morning through O'Reilly's believe it or not. I can't find a OEM or similar pump. Just rebuild kits...

    Brand new fuel line. Brand new primer bulb. Now my line is like 6-8feet long would that matter? And Ive heard the primer needs to be in a vertical position not laying horizontal. Is that true? And i found a couple of issues when I got it home. 1. The fresh fuel is no good. Not sure if...

    1956 Johnson FD-10 15hp.

    Well got it in the lake. Unsure if its a pump issue or a carb issue. It'll run decent then act like it cant get fuel. If I keep pressure on the primer it'll stay running. Though if I let it run out and stall. I can pull yhe line off the fuel pump and pull it over and its pumping fuel when I...

    1956 Johnson FD-10 15hp.

    Had to order one. I was keeping a close eye on the water flow. Just wanted to tinker with it today and see how it ran when it got some heat into it. Super impressed with how easy this thing starts just 2 pulls. A pull with choke then 1 more with choke off and its running. Can that glass fuel...

    Gave it some lengthy run time today in a barrel and its pretty good. Starts very easy. Pumps water good and i kept checking and the power head stayed just warm to the touch.
