    Hi, I have an old (1984) 40hp Johnson Seahorse serial number: J40ELCR It runs great and has good compression and not a spec of rust, but it does not have PTT, which is aggravating. I am having trouble sourcing a unit, and need help. I really don't want to spend more than 300 for one, because...

    Missing carb jets/ 200 black max

    This question pertains to problems I am having with a 1988 200hp 2.4L black max. So I thought I was in for a carb cleaning when I started getting a rough idle. My compression is 125+ across the board. When I pulled the carbs, I found these jets missing on the #1 and #3 carb...

    Easy question for the pro's!!!!!

    How many GALLONS PER HOUR can I expect to burn with a 1988 200hp 2.4liter black max? I have this motor on a V20 Wellcraft. I am using a 17 pitch prop and at WOt get 6000 RPM. I know fuel consumption is not a linear thing, so I am curious about WOT consumption and 3000, and then again at 4000...

    Poppet Valve

    I have a 200 hp 1988 Merc Black Max. Serial number OB242097. The poppet valve is giving me a hard time. In the manual it is "design one". It looks like 2 circles that are connected if that helps. Here's the problem; last week I noticed water coming out of the weep hole on the poppet valve, so I...

    How do you.......

    I don't really know how to describe it, but I'll try, here goes. On the bow of those old runabouts, and I am talking about the 1930's looking wooden "chris Craft-ish" Runabouts that are all mahogany or some other nice wood. Usually on the bow or topsides of boats like that, there is a wooden...

    Is there a better way?

    I was considering that the 2 switchbox system is kind of a zoo in that there are a lot of parts to fail. Mercury switchboxes aren't indestructable, and frankly, while they do hold up for a while, I was wondering if there is a better electronic ignition that could be retrofitted to the Black max...
