'Knowing what i know about the Polaris Fuji motors ( which is what you have) they are KNOWN for fuel related issues. The fuel pumps are weak, fuel lines go bad, the fuel select valves go bad, and your carburetors are 15+ years old, and probably have never been rebuilt. I would strongly suggest doing some routine maintenance to your ski. Rebuild the carburetors, update your fuel system to a triple outlet fuel pump, replace lines, etc. I think you will then find it will start and run properly.

If you DO NOT do this, you will run the risk of running lean, and ultimately engine failure.' Friscoboater's Fuji threads and (scroll down to find the Polaris related clips) If the metal shell of the electrical box touches the battery positive post it will burn up the Black stator ground wire The stock connection for the heavy black battery cable to the engine is actually a small bolt on the engine bed plate, not the engine itself. If the bolts connecting the bed plate into the bottom of the engine became corroded or loose it will create a poor electrical connection between bed plate and engine, which will cause electrical problems (poor engine ground back to the battery). One symptom of a poor battery ground is that the thin black wire to the battery gets warm when the engine is cranking.

Cranking may or may not be noticeably slower with a poor battery ground, but it will be better with a good solid ground from battery to engine. Since it is impossible to see those engine bed plate bolts underneath the bed plate, they are easy to ignore. Move the engine end of the heavy black battery cable to one of the intake manifold studs at the PTO cylinder. That ensures the negative cable really does have a solid, zero ohm electrical connection to the engine itself, not just to the bed plate. Makes sure both ends of both battery cables are clean and provide solid metal-to-metal contact. Note: If moving the battery negative cable solves the electrical problem If they are loose you must tighten them.

Some 650 and 750 Fuji engine models have a small metal flow restrictor (Polaris part number 5020773) inserted inside the return fuel line, about one inch from the last carburetor. It looks like a brass plug in the return fuel line, and it has a tiny hole driller through the center. The restrictor is used to boost fuel pressure inside the carburetors, and is in addition to the internal flow restriction in the Mikuni SBN carburetor. The restrictor was present in 1994 and 1995 SL650, SL650 STD, SL750, and SLT models.

May have also been used in some 1993 650 or 750 engines. It was not used on the Fuji 780 or 785 engines. If the fuel lines are replaced and the restrictor is accidentally discarded with the old fuel hose then the carburetors will not have enough fuel pressure to run the engine properly at high throttle levels, and lean burn piston damage can occur. Consider upgrading the pre-1995 fuel tank venting to the 1995 specification Tip: If opening the gas cap releases a very strong whoosh of air pressure, Sticking check valves are difficult to properly clean, so just replace the old valves.

7052118 VALVE,VACUUM CHECK 7051015 VALVE,CHECK,RELIEF 7052111 FITTING,TEE On any model with two check valves, make sure the existing check valves really do open and flow air under mild pressure (max 2PSI) in one direction, and seal under mild air pressure in the other direction. Bad check valves can cause excess air pressure or excess vacuum inside the fuel tank. Neither is good. Replace the old fuel lines inside the fuel tank (1992-1994, some 1995 models).

Polaris used flexible fuel lines inside the fuel tanks on all 1992-1994 models and on some 1995 models (1995 SLT and 1995 SL650 STD have hoses inside the fuel tank). Later in 1995 production switched to one-piece metal pickup assembly inside the fuel tank. Note: Polaris part number 7052037, 7052081 and aftermarket from. If you have two intake hoses inside the tank, the 'Reserve' intake reaches to the bottom of the fuel tank and the 'Main' hose is about 2 inches shorter. Be sure to use quality replacement fuel hose which is rated for continuous submersion in gasoline and is rated for ethanol blended fuel. A fuel leak, even a small one, is. And From about 1994-2002, the factory installed gray Tempo brand fuel hose chemically reacts where it connects to metal fittings, creating a greenish or bluish goo inside the hose that clogs the fuel system and carburetors, causing lean fuel delivery and burned pistons.

The outside of the Tempo fuel line can look and feel just fine despite the internal degradation., the same gray Tempo hoses were also used on Polaris and Yamaha PWC. Depending on the model you have you will need 20 feet of fuel line, maybe a bit more. If your fuel selector valve is leaking air into the fuel system, you will have problems and risk engine damage (lean burn). Refurbish the selector valve internal seals, or replace the valve.

The is no longer available, but Avoid gasoline flooding of the engine, and possible engine damage, fire, or hull explosion. The stock 650 and 750 air intake flame arrestor is restrictive, and reduces engine power somewhat. Some owners remove the rubber elbow from the intake. If you retain the rubber intake elbow on the flame arrestor, be sure the rubber intake opening faces down, not upwards.

If you remove the elbow, the high speed adjusting screws on all three carburetors may need to be opened up (turn anti-clockwise) a little. You can upgrade to the OEM flame arrestor versions used on the 780 and 785 engines, but the carburetors may need adjusting for correct fuel mixture. See the 'Piston Wash' notes. How to figure out which cylinder is running poorly By testing the cylinders one at a time, you can narrow down which cylinder is dead or weak. Ground the ignition wires for all but one cylinder, and see if it will start (you may need to squeeze the throttle to get it to run). If it does, ground that plug wire, and test the next cylinder. Each single cylinder should run the engine about the same.

The 'one cylinder at a time' test will reveal a cylinder that is not producing power due to mechanical problems (low compression, broken reeds, out of phase/index crank shaft), fuel problems (carburetor, fuel delivery), or something wrong with the spark (coil, wire, plug). In this example, there were two problems. Incorrect spark plug firing order (wrong sequence of spark plug wires) and the PTO carb was missing a part! Note: Normal/stock Fuji 650/750/780 engines do not have sequential spark. This particular tweaked Fuji engine in the video happens to have an aftermarket ignition system which has sequential spark, similar to the Pro 785 engines. Engine rebuilding - gaskets For the engine assembly (cylinder, cylinder head, intake, exhaust) you can use either genuine Polaris OEM gaskets or are available from for both Fuji and red domestic engines 6207 and 6307 bearings are used in many Polaris watercraft 2-stroke engines are somewhat unique. In the case of the Fuji engine, the 6207 is pinned and the 6307 is pinned and also has a snap ring.

The pin is used to keep the outer race from spinning in the case. You can use the unpinned bearing. Use Loctite 680 Green on the outer race to secure them.
