Running at that RPM for extended times should not be an issue as long as the engine is able to operate within the designated RPM range at wide open throttle.

MPI means Multi Port Injected. The WOT rpm for your engine is 4600-4800. Your manual says 4600-5200 but the high end of the range for your engine is 4800.

We have never tested the FAE system so I have no factual data. I would have one concern that since the exhaust is expelled under the surface of the water that the exhaust back-pressure when the boat...

That 70A alternator is Indmar P/N 575010. You can get one from inboardonline.com. Better price than skidim.

That article was based on data from an LSA engine which is our supercharged small block engine. That engine uses Mobil 1 fully synthetic 5W30 oil as specified by General Motors. The data is...

Get the solenoid for the 4 wire PG260 starter.

Did you look in your engine Operator's Manual? All that information is there. If you don't have one, here is a link.

Your engine actually has two fuel pumps. That part with the filter under it is the high pressure pump and the other one is a high volume low pressure pump that draws fuel from the tank and feeds the...

Here is a link that will take you to a diagram that I believe will apply to your engine.

Shell Rotella 15W40 is very good choice.

the drain plug is an 1/8 NPT brass pipe plug.

The 11 foot pound torque is for the intake manifold, not exhaust. Using a gasket is OK but the RTV works very well. We have been building engines that way for the past 30 years or so. There is no...

Could be the drive plate that bolts to the flyheel. The center portion where the input shaft of the transmission plugs in has springs to absorb the torque when shifting into gear. If one or more of...

The Indmar P/N Is S605030.

EFI engines work like that but not carbureted engines. Carbureted engines have fuel pump safety switches like I described.

The fuel pump should not run with the key in the on position. There is a fuel pump safety switch near the distributor that should only allow the pump to run when the engine is either cranking to try...

They don't really get dirty ... not too much dust/dirt on the water. A cleaning once a year is recommended.

Doesit look like this one? That flame arrestor has more air fow capacity than your engine really needs. You can clean it with carb cleaner or even soap and waer and a brush. Just make sure it is dry...

What model engine do you have? Most Indmar engines already have K&N Flame Arrestors. If yours looks like this it is a K&N. You need to make sure that if you install any flame arrestor that is...

The oil dipstick goes through the water chamber cover. If the gasket that seals around the dipstick hole is bad,water can run right down the dipstick hole and into the oil reservoir.

Those plugs are pipe plugs with tapered threads. They are not meant to go in all the way.The extra plug is probably the drain plug for the transmission cooler.

The 50 hour recommendation is for conventional as well as synthetic oil. Marine engines run relatively cold compared to automotive engines. We use 160 degree thermostats while automotive engines run...

That oil meets or exceeds the specificationsfor your engine. Generally, any "brand name" 15W40 oil will meet or exceed the mininmum specifications. Follow the link to the API website that explains...
