    Hi, so I went to the lake yesterday an hit some rocks after launching the boat and it stalled, not a big hit apparently although after that we started boating no major issues at low speed then when I started to increase speed motor went high in revs but no more speed, felt like no power was...

    Mercontrol Wiring to 1978 Mercury 500 Thunderbolt

    So I went the easy route, my harness had like 2 foot extra in length so I was able to just repair the damaged wire and is working good now, I did noticed all the insulation of the cables is falling into pieces so I plan to change the whole harness soon.

    Nobody fishing?

    First time I hook a Tilapia, I don't know how is called this in english, not common to get one of this with a lure, and yesterday I fished 2 of them, not very fun the rod just felt heavy, no fight at all. Good experience anyways.

    Tachometer for 1978 Mercury 500 Thunderbolt

    The boat is 15' long, I'm unsure of the lenght of the trip but we were running average 25-26 mph, that means that over all it was 1.3 hours more or less. According to what I have read the rle of thumb is that my 50 hp will burn 5 gph. It should had been 6.5 but we burned 10. There are things to...

    Tachometer for 1978 Mercury 500 Thunderbolt

    Hi, what kind of tachometer I need for my outboard? 1978 Mercury 500 Thunderbolt 50HP S/N 4967035, after some tweaks I think it is running good but even being a small engine it is a thirsty one, it consumes too much gas to what I believe should be doing, we usually go WOT I want to change that...

    Not shifting to reverse / 1978 Mercury 500 Thunderbolt 50HP

    solved with new cables, definetely the not shifting was due to the very damaged cables I had, I got the 13' same as the ones it had before, I think they are too long but I didn't wanted to risk going for the shorter ones.

    Milky fuel in carb intake force 85hp

    Thanks, altough I did find the Part number in Crowleymarine.com, and there's one availble in ebay so I think I will go for that one, it is a lot of work to get that is not worth risking to make one myself. Would that seal cause the issues I'm having, still will make the test with the cowling...

    Milky fuel in carb intake force 85hp

    Last time I did run without the cowling cover and I noticed it ran better with out it, I don't know if that is better air flow but of course it is intended to run with the cover so I put it back again. Will take a look to the wires you mention in the stator and trigger.

    Milky fuel in carb intake force 85hp

    Forgot to mention when I was in the rebuild process I took a look to the reeds and all seemed to be closing except for one, you could see a tiny light through, but I believe its in the acceptable range.

    Milky fuel in carb intake force 85hp

    Hi Jiggz we did check on the primer bulb that was a common issue in other boat so now almost every time something fails that is one of the first things we check, I believe it is not the issue it does not collapses and stays firm all the time, if you try to press it when its starting to die it...
