    40Hp OMC Trim and Tilt

    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...

    No load revving

    I would like to know what the real deal story is on revving up a 2-stroke with no load. What are the tolerances? What is the failure/ consequence for over revving. Is it all just B.S.? I have heard all kinds of horror stories about catastrophic engine failures due to someone over revving it in...

    Gearcase Tools

    Where can I get mercury Gearcase tools? I graduated from a marine technical school in florida and I work as a technician, but I am pretty far removed from the general industry if that makes any sence.

    Will this work?

    I have a 1988 mercury 200 hp black max. The trim and tilt leaks down pretty bad and came across these on craigslist and I was wondering if I could rob the T&T out of one of them and re-sell the rest. BUT, will it fit???? Does anyone know if the T&t out of a 275 will fit my 200...

    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...

    200 Ptt

    Does anyone know where I can get the spanner wrench for the main ram of my PTT so I can replace the seals? Maybe a part number? My PTT works, it just leaks down over time and under power. I refuse to pay 800 bucks for a re-man unit. Has anyone ever re-sealed one? Any tips? Is it just the top...

I removed the Fuel injectors on a yamaha f90 today that has sat for 3 years and there was all kinds of debris in the "little holes" and in the intake side of the injector there was a white chalky substance that I assumed was aluminum oxide...
