    Starter wiring help, 90 2 stroke

    Go on the maxrules site and grab a wiring diagram. Now trace the unconnected wires and see where they go. Connect per wiring diagram. Relay primary windings must have a ground to operate. The PTT motor must be grounded thru the relay's secondary winding to operate as well. That larger...

    Shifter question?

    Better performance from changing the controls? Not sure I understand the question. If the shifter is adjusted and installed correctly, the motor should shift properly. If the throttle cable is adjusted properly, the throttle should open all the way.

    How can I raise my 1977 1150 Mercury because I want to add oil to the power/trim unit

    As Alumarine says, turn the knurled knob, at the very bottom of the PTT motor/reservoir. Now take an Ibuprofen and grab the gearcase with two hands and lift it to tilt it. Initially it will be difficult, but will get a bit easier. Use the manual tilt lock (dog ears on midsection) to hold it...

    Engine Cover/Rear Decking

    I built the doghouse out of 1/2 plywood. The front seams were fastened with fiberglass cloth and resin. The rear edge was strengthened with 2X2 lumber, screwed to the plywood. Cover the plywood with polyurethane inside and out, and cover with a rug or vinyl to match the seats.

    89 Sea Ray Bowrider starboard back padding upholstery repair

    My '88 SeaRay 18 footer had nuts holding the bow padding to the hull. Pull up the base cushions and stick your hand up, behind the pad to find them.

    Trim/tilt blows engine main fuse - Johnson 115hp Oceanrunner

    The wiring is likely shorted to ground somewhere in the engine harness, Look for melted wires on the engine harness. If '96 and newer there are 2 connectors on port side of motor. Look there for melt, and then move to under dashboard wiring.

    Intermittent Trim issue - late 80s Mercury 115

    So, the PTT system is the trim pump/reservoir in the boat and twin trim cylinders outboard of the transom bracket? I think the problem is electrical supply to the Trim Pump motor. You can test this by using a jumper cable from the battery positive post to the green and then blue wire that run...

    Carburetor frustration

    The idle passages are in the throttle bodies, not the carbs. Did you get them clean? New side plate gaskets on the throttle bodies? I pulled the side covers off and sprayed the idle needles to clean 'em up. They have a mid range orifice. did you blow that out? The Spaghetti seals on the...

    Insane good tower of power fuel economy?

    Merc IL6 were very compact and light for their power. Even by today's standards. Most of their power was at mid RPM range however. Low power was less. On my Avenger, I would use full throttle to get her to plane. At that point (3000RPM, about 30MPH), she would turn into a rocket and...

    Insane good tower of power fuel economy?

    My Avenger also has minimal foam under the deck, however, it has a chunk under the bow, and there is room for more under the splashwell. She does float when swamped, fortunately. Foam also is used to support the hull, so less stringers and frames are needed. Hopefully your hull didn't count...

    Boat refueling

    The problem with gas caddys is that they hold 12 gal. They are heavy to lift into the trunk of the car after filling, and out again. They then take 2 hands to drag to the boat. I find 5 or 6 gal Jerry cans better. They pack more tightly in the trunk, are half the weight and you can carry 2...

    1975 115 2-stroke inline 6 WOT problems

    Those motors never had a fuel filter. They have a screen in the fuel pump An inline filter might restrict fuel. I would remove it for testing and if she passes, install a 20GPH water separator. There are also screens under the brass elbows and tees on the carb covers. They do not usually...

    Mercury Tilt switch in remote control question 88688a26

    Toggle switch on handle? They can get water in them, which completes the up circuit. See if you can blow it out with some wd-40 or equivalent.

    1975 115 2-stroke inline 6 WOT problems

    What prop pitch and what boat? You may be simply over propped. Squeeze the primer bulb at WOT and see if she will rev up higher. If so, replace the fuel lines with 3/8". However, I think 5/16 fuel lines are OK, but the fuel pump, if the "figure 8-shaped" one can be marginal. If primer bulb...

    Insane good tower of power fuel economy?

    That is very good performance. I had a 1500 on my 16 foot Avenger and had the same top speed, but I do not think the fuel economy was as good. I think you made a mistake by not reinstalling the foam floatation. It only weighs a few pounds, and could save your life. That boat is very likely...

    Modifications/equipment changes required to repower from '95 Force 120 to '76 Mercury 1500

    I would be surprised if the transom brackets will interchange. A simple test is to drop the 4 sheet metal screws that hold on the lowermost cowling. Count the powerhead mounting bolts. See if the force has the same amount. Since the powerhead is the Chrysler design, I do not expect much to...

    Mercury 850 Thunderbolt 85 hp 2 stroke leaks gas out top carburetor before and after carburetor rebuilds.

    Gee, can you give us some more info? What year motor? Does she have spark? Did you choke the daylights out of her? They need heavy choke to start.

    1978 Mercury Black Max V1500, Surging at high throttle.

    Don't screw around, use Merc wires. You can get them aftermarket and save some $. Sierra likely makes them and they are likely avail in a lot of places. You must do a link and synch. If boat shops tell you different, they are nuts. You will want an OEM service manual. Succinctly, when the...

    1980 mercury 50hp carby

    Take a look at the parts listing on a site such as crowleymarine. My '77 had a plastic grating over the carbs. It kept the large stuff like rodents out of the motor.
