    Adding another rectifier

    Gee, unless you are running some powerful electronics with the engine off, 2 batteries should have lots of power for your electronics. if you run powerful electronics, set the battery switch to the odd battery on odd days and even battery on even days, when you stop the engine. After starting...

    Mercury 1977 200HP with exteral Trim/Tilt motor inside boat mount.

    Usually they are mounted under the splashwell, but above the bilge. I had one on my 16 footer, and if fit fine. I did not think Merc made a 200HP motor in 1977. They did make a 175HPV6 Black Max.

    Yamaha binnacle for Mercury outboard

    Is the binnacle a yamaha brand, or universal? If universal, there should be some way of adapting it. Mercs need to have the throttle pushed closed, unlike Johnnyrudes, which push the throttle open. Not sure what Yamaha needs.

    1988 SeaRay Seville Throttle

    Maybe the insulation on the PTT wires is worn away. If it is the same throttle that I had on my'88 SeaRay, there are two screws that hold a cover plate over the wires. I would remove it and see what is rubbing.

    Trim Tab Anode

    Merc makes at least 3 different anodes for above and behind the prop. One is flat and usually used for boats with power steering. One has a small fin and is used with props with extra rake. One has a larger fin and is used with standard props. If the boat pulls, choose one with the largest...

    Adding another rectifier

    What are you trying to accomplish? if you simply want both batteries to charge, connect them via a battery switch, and set it to both. You could also just connect both batteries in parallel with cables. If you want to isolate the batteries from each other, say one battery for starting and...

    1989 Sea Ray 160

    There are only three places I could think of for the fuel to go. 1) Your fuel pump has a diaphragm between the crankcase and the fuel line. If it gets a hole in it, fuel can drain into the crankcase. 2) If the check valves in the primer bulb are bad, fuel can drain back into the fuel tank...

    23-24 foot vs 26-28 foot pros and cons?

    Putting a dual prop outdrive on a too small engine for the boat, does not fix the problem. Dual props track straighter, but do not manufacture HP.

    Fuel system fail on new boat

    Heck, take a portable tank and fuel line with you for test. Connect the built in tank to the big motor ONLY and see if it works. if some of the "plumbing" to either motor leaks air into the fuel line, you will have fuel starvation.

    8-pin cable plug harness

    The middle pin looks to be the +12VDC power wire. That would send battery power to the helm. Without it the motor would not crank, but would continue to run. If the boat side of the harness is good, you could replace the engine harness, pretty easily. Heck the boat harnesses are not all that...

    1998 johnson 115 lower unit leak

    The only reasons the gear oil would leak with new seals is if the bearings allow prop shaft movement that the seal cannot cover, a nick in the propshaft, bearing carrier or housing ripped the Oring or seal or the housing is out of round, or scored. You are only supposed to put grease on the...

    23-24 foot vs 26-28 foot pros and cons?

    26 footers with single 305/350 I/O power can be dogs. Cruising (actually getting on plane) means everyone forward, into the cabin until she planes, then everyone back to their previous positions. Watersports with them suck more. Try to get one with a big block engine. They at least have more...

    Looking for part number to buy a red OMC/Johnson remote tilt/trim switch on throttle handle

    Gee, I am pretty sure you could get an aftermarket control with wiring, key and trim switch for $150-$200. They are not real hard to put in. You might check crowleymarine for the switch and get a part number, Flea Bay or someone might have NOS. Look at the accessories section for your year...

    Grinding on hull for floor replacement

    I would feather the edge of the old fiberglass. When you lay the new glass to tie the new deck too the hull, make the first layer 1/4" overlap, the second layer 1/2" overlap and so on. In your case use several layers of light cloth, versus chop strand mat. That will give the smoothest joint...

    Engine will not keep running without enricher being pushed non stop.

    Carb cleaner is fine for carbs, at least the aluminum part of them. It may (may) harm some of the plastic pieces. If the shop that cleaned the carbs was trustworthy, they should be clean. Did they (or you) replace the inlet needle, seat, float and gaskets? That is a normal part of the...

    Need the location for idle adjust arm

    You should get a service manual and check the link and synch for that motor. Simply raising the idle speed is not the best way to fix it. All the adjustments are on, or effect the throttle arm.

    Mercury 1150 115hp(1977 I believe)

    as Merc 850 said, that motor is the best "FrankenMerc" I have ever seen. That silver block means it is old, pre 70's.

    Transom question

    Boat ratings usually specify max HP, but not weight. As long as you are at or under Max HP, you should be fine. The extra weight should not make any difference. You do walk back to the motor area, right? You weigh more than 100 # and the boat doesn't sink, right?

    Engine Cover/Rear Decking

    The doghouse on my SeaRay tilted forward on hinges, and the hinges from it to the deck could separate, so it could be removed completely. Not a bad design.

    Mercury 1150 115hp(1977 I believe)

    It should be on the transom bracket, in the front top. The thumb screws on your motor were a bit different than the ones on my '77 Merc 1500. Decals were the same. You may therefore have a 1976 motor. The factory service manual I had covered all Merc motors from about 1980, back to 1971...
