    No Signal To Temperature Gauge

    I replaced my 1993 Mercury 150 hp 2 stroke Black Max outboard with a 2023 Mercury 150 hp Four Stroke outboard. The speedometer, tachometer, and voltmeter are working fine, but the temperature gauge is not getting any signal. An 8 pin to 14 pin adapter was used. Any idea why the temperature...

    Throttle Trim Switch for 1993 Mercury 150 hp Outboard

    About a month ago my outboard engine trimmed up on its own. I replaced the trim solenoids and thought I fixed the problem. Today the engine again trimmed up on its own. I now think the throttle trim switch might be bad. The replacement trim switch part numbers I found are: 87-18286A43...

    Up Trim Solenoid

    Last time I was out my up trim solenoid stuck in the closed position. I was able to get back to the dock by holding the down trim button in to keep the engine in the water. Tapping on it with a screwdriver handle got it working again but I'm not sure for how long. I'll be replacing both the...

    Effect of Weight

    Last year because of COVID we didn't take anyone out boating with us. It was our first year with our Sea Ray 200 OV and it would cruise at 32 mph at 4000 rpm with the two of us onboard. Two weeks ago the two of us took it out for the first run of the season and it ran at 32 mph at 4000 rpm...

    Hull Cleaner

    I'm going to be cleaning my hull with West Marine Instant Hull cleaner (oxalic acid solution) before launching. I've read that some people use a brush to apply it, while others use a spray bottle. Also, some people use a garden hose to wash it off while others use a pressure washer. What is...

    Fuel Gauge Ohm Values

    Does anyone know the fuel gauge ohm values Sea Ray was using in 1993? The PO had the fuel sender replaced with an American Standard sender (Full = 33.5 ohms, Mid = 103 ohms, Empty = 240 ohms). I measured the ohm values at the sender. Full measured at 33 ohms. 60% Full measured at 90 ohms. My...

    New Marina Planned Across From Delaware City

    Fort Dupont Redevelopment is planning to build a 120 slip marina across the canal from Delaware City ( https://fortdupont.org/marina-village/ ). Not sure about the timing of the construction. A hotel is also planned.

    Difference between 135 hp and 150 hp Black Max Outboard

    From 1992 to 1999 Mercury used the same powerhead, gear ratio, and propeller for the 135 hp Black Max and 150 hp Black Max. I can't figure out what the difference was between the 135 hp and the 150 hp. I have the 150 hp Black Max and my performance is comparable to someone who has the same...

    M-Y Wedge

    Has anyone used the m-y wedge (m-ywedge.com) instead of a transom saver? It looks like a good idea but I'm not sure about only using one. I'm worried there would be a twisting force on the outboard. I'm thinking of using two to make sure the force is evenly distributed.

    Future of Sea Ray

    Sea Ray is only building bowriders now. The 320 Sundancer has a small cabin, but is basically a large bowrider. Is this a smart direction for Sea Ray to go? They will be competing with Regal, Crownline, Chaparral, and Four Winns. They will also be competing indirectly with more entry level...

    Mercury Outboard Cooling System

    I just had the water pump impeller, thermostats, and poppet valve replaced on my 1993 Mercury 150 hp Black Max outboard. The mechanic said the old thermostats and the old poppet valve were constantly open. This might explain why my engine temperature would be 130 degrees when I was idling off...

    Starting 2 Stroke 150 hp Outboard

    Once I get my 150 hp 2 stroke outboard started it runs great. It's taking me a lot of trial and error though to initially get it started. Here's the list of parameters I'm working with: Fuel bulb: squeeze or not squeeze, if squeeze, how many times Push in choke (at key): use or not use...

    Speedometer

    This past weekend my speedometer quit working. It briefly indicated about half the actual speed and then quit all together. Most likely the inlet on the outboard lower unit is blocked with something. I'll also check the back of the gauge to make sure the tube is still connected. Any other...

    Tachometer

    The tachometer needle on my 1993 Sea Ray 200 Overnighter (150 hp Mercury outboard) is at 400 rpm when the key is off. When the engine is idling in neutral the tachometer usually is indicating ~1000 rpm. Sometimes when I start the engine the tachometer is indicating ~3000 rpm when the engine is...

    Black Max Tell Tale Stream

    I have a 1993 Mercury 150 hp Black Max outboard. Running it on a trailer today with a hose there was no water coming out of the tell tale. Since it was on a trailer I could see the normal amount of water was coming out of the thru hub exhaust so I know the engine was getting water. Also, the...

    Windshield Wiper

    We recently purchased a 1993 Sea Ray 200 Overnighter OB. Our last two boats had a windshield wiper but this one doesn't. Does anyone know of a windshield wiper that would be an easy aftermarket installation? Thanks for any ideas you can suggest.

    Battery Management

    The 200 Overnighter I recently purchased had a second battery installed by the previous owner. The 1/2/Both switch is wired to the engine so the battery selected starts the engine and receives charging from the alternator. The electrical bus and bilge pump, however, are hardwired to Battery 1...
