I know some things should be marine specific for safety reason but stuff like distributor cap / rotor / fuel filters / plug wires etc
Does anyone have or is there already a thread where some have started to document part numbers that interchange so we don’t get hosed by having to buy the marked up marine version?
There is not a dedicated forum thread for this, but most of us have helped each other out with this exact thing.
My 2015 MOJO I have a Google doc that I store fluid types, spark plugs, belts, etc. part numbers that I have crossed already.
So....what do you need?
ThanksQuote:

Spark plug wires (anything different other than the special cut length on the marine version?)
Cap and rotor
Fuel filter
Anything else that’s suggested to replace with mid of the road type hours on the engine?
Not sure my plug wires are "marine" rated. I changed plugs last season and inspected the wires. They look like standard high performance 8mm wires for a Raptor f150. My old boat had cap, rotor, etc. Only difference from marine and auto was a small anti-rust coating and the price. The coil was different. The mechanical fuel pump had a ground wire on the marine version and cost 4x what the auto version was.
Be careful though some things need to be marine rated. I'm sure the fuel filter is something you can get at a parts store. 325 is chevy based so not to bad to cross parts.
had to buy similar parts for the old supra that had the ext340 cat motor. found plug wires on ebay new for a steal and the rest of the stuff came from dealer. they weren't gouging too much back then.
i'd be cautious on the fuel filter if you don't have any issues with vaporlock. the older boats are notorious for it and it all stems from filter/pump location. if you have no issues, keep it factory to ensure it stays issue-free. my .02 anyway :)
not much else to replace until you start tossing codes for burned out sensors.
Anyone know the equivelant to the:
556345GM
and
556346
I would take my OEM parts to the auto parts store but I don't have access to the boat for awhile.
I tried searching online but didn't see any cross reference.
When I look at similar images it looks like the
Quicksilver 8M0061335 1 Distributor Cap and 1 Rotor
is very similar, and I could probably cross reference that one.
Search your local autoparts store for 1999 Chevy Silverado 5.7L 350 parts.Quote:

However, I needed a mechanical fuel pump for a 3.0L 4cyl mercruiser motor once and the 2.8L camaro pump was the exact same for 1/4 the price and in-stock at my local NAPA. Just have to check and be safe!
Thanks, that's what I was looking for (a starter reference to a make/model of the equivalent car/truck to base the parts off of).Quote:

These are good for reference.

Hey Loud,
The Assualt 325 is based on the GM Vortec 5700 platform. Basically a truck motor that has been marine fitted. 1999/2000 was the last year for that engine before everything became LS based.
If you need plugs, wires, etc. should be the same deal.
On rock auto when I look for the 99 silverado it comes up with a 5.3 V8 but if I look up the C1500 pickup they have the 5.7 V8
"Is that with or without air?" LOL! Some of you might understand my lame humor in that comment.

1999 is a mid-year cycle change. Use 1998 Silverado for Vortec 5700 parts. The C1500 is the same also. 1998.5 the switched form 5.0/5.7 engine to 5.3 motors and later 6.0.Quote:

Is the 6th digit in the vin a "U"? LOL!Quote:

I know what you are talking about. For a short time in college I worked at Pepboys for a stint. I grew up around engines and vehicles so many times I would skip the questions and just pull the parts. If the person wanted to be rude, I would ask every question I could think of and "maybe" it was in stock and "maybe not". Sometimes those question did matter, but other time you question why a 5.0 mustang has 4 different type of alternators! (Not picking on Ford, just an example)Quote:

But, I guess that's my point. Sometimes questions were asked that just didn't matter. That's how I always knew if the person behind the counter knew cars or not. And sometimes the guy would do just as you said and skip right through all that to get to the part numbers.Quote:
