    1996 venom 200 double problems tachometer/reverse

    I have a 1998 Johnny 150HPV6. I have had some issues where the shift rod gets hung up due to corrosion, and will not go down into reverse. The fix is to drop the gearcase and figure out what is jamming the shift rod. You might like to see if this is your issue. Remove the cowling. Spin the...

    Boat floor soft only around ski locker

    I had an '88 SeaRay with a ski well. When they installed the ski well cover they cut the plywood decking out, but did not seal the edges of the plywood. Moisture founds it's way in and rot ensued. Unfortunately, the moisture also rotted the floor of the ski well and the keel support under it...

    Fuel vent question

    Gee, your fuel tank looks to be made of fiberglass. If so, the alcohol in today's gasoline can dissolve some of it's components possibly causing leaks. I agree that the tank vent looks unusual. As for your filling issues. You normally want the vent fitting on the tank to be as far forward as...

    1987 Mercury 45hp classic 50 control cable anchor

    Here is a diagram of the area. There were a lot of 50HP models in 1987, so I had to pick one, but the cable clamp stuff is pretty common. https://www.crowleymarine.com/mercury/oem-parts/outboard/1987/1050717/shift-linkage-and-exhaust-plate?ref=1 Most stuff is d/c, but should be avail at...

    1980 Avenger weight and hp rating

    Gee, I have owned a '74 16' Avenger since 1980. It is rated for 85HP, but I ran a Merc 1500 for decades and now I run a Merc 135HPV6. It has a 3/8" thick aluminum plate covering most of the transom. That dinky aluminum plate on the transom in the photo, is clearly not holding the transom...

    No Spark, feels like I’ve tried everything.

    Gee, how exactly did you check the timing, if you have no spark?

    1983 Mercury 50 HP 4 cylinder Electric Start Wiring Diagram

    Here is likely wiring diagram in color. https://maxrules.com/oldmercs/Wiring/1966ona/60.jpg If your wire colors match, then red is +12VDC; black is ground; blk/yellow is ign killer; yellow/black is choke solenoid; purple is power from ign switch; grey is tach signal; yellow/red is starter...

    50 hp Merc 1985

    Look on the maxrules website for the wiring diagram and year. Your motor's serial no. looks to be a 1982. You probably have the new, common wire colors such as purple for ign power, but those 4-cylinder 50HP motors were really popular, so they were made the same for years after other models...

    Bouncing Tilt and Trim on Way Down

    Well, bleed the unit, and grease the parts that move.

    1979 Mercury 80 HP power trim

    The trim rams should retract all the way into the trim cylinders, when the motor is full up. At that point, you should be able to lift the gearcase by hand to use the manual locks.

    Bouncing Tilt and Trim on Way Down

    Normally that is caused by the motor binding on the tilt tube or something similar. Grease the tilt rod, and make sure nothing else is binding.

    1979 Mercury 80 HP power trim

    Merc850, I think he is well past the original wiring. He seems to have simplified it to a single switch and three wires. If his motor doesn't trim all the way under PTT influence, I would think it mechanical, or some other issue.

    Fuel Pump for 1997 9.9 mercury four stroke

    I was unable to find a cross ref from your serial number to a Yammie. Take a couple of pictures of your motor including the powerhead w/o cowling. Go on the crowleymarine web site and work your way thru the yamaha 9.9HP motor parts diagrams of your year until it matches yours. Now see if...

    Partial transom repair

    Watch the top corners of the transom for cracks. That is usually where they start. You going to junk the hull in a couple of years?

    1979 Mercury 80 HP power trim

    Gee, jumper the up solenoid at the pump reservoir so it runs. See how high it goes. If not all the way up, something mechanical is amiss. Watch those dog ear-shaped manual tilt locks as they can bind up the triple clamp. Merc did make PTT units for lower HP motors, say the popular...

    High-Speed Jet NLA??

    It sounds like the slot for the screwdriver is partially stripped. Normally that does not damage the jets. If the hole thru the brass jet is rough, that could be an issue. Some of those carbs have intermediate air orifices, w/o air filters. I have found that they can clog. You might clean...

    1979 Mercury 80 HP power trim

    I did not really understand your post. However, wiring for your PTT system is real simple without the trim limit switch. The PTT pump/reservoir is connected by dedicated battery cables to the battery. The pump/reservoir body is connected to the ground cable, as is the black lead from the PTT...

    Fuel Pump for 1997 9.9 mercury four stroke

    They seem to be pretty scarce. Here is one from the UK (I think). https://ouboaen.com/825470t One from Wisconsin: https://www.2040-parts.com/825470-fuel-pump-mercury-outboards-9-9-hp-4-stroke-1995-1998-i1380848/ Some rebuild parts are at Marineengine.com If truly a Yamaha part, you will need...

    High-Speed Jet NLA??

    Gee, the main carb jet for your motor is: https://www.crowleymarine.com/evinrude/products/0328543-58d-orifice It is still D/C, so you would need to look at the used/junk parts arena. Why do you need new ones? They never wear out.

    2019 4.3 Mercruiser/Alpha One Outdrive

    Normally the dia of a prop is set by the OEM, and you pick one based on pitch. I am therefore not sure how much choice of dia you will have. Your RPM and speed numbers are very unusual. Not many 4.3L engines can swing a 23P prop at 6000 RPM and only get 32MPH. I would think you need to...
