belts

2003 ski 196 with a 330 excaliber

does anybody have a part number/cross refrence to both v-belts for this engine. I would like to just walk into a parts store, instead of having them shipped from a CC dealer.

Thanks!!!!

RE: belts

White Lake has them pretty cheap and they're a site sponsor. I got my impellar's cheaper there than they were online, plus I got to support the site!!!

RE: belts

Get them from NAPA, I got mine there last year. Part numbers 7455 and 9305. These are direct replacement "vee" belts. My boat is an 03 SAN with the raw water pump driven by a seperate belt off the crank. My boat doesn't have the serpentine belt. Sounds like yours is similar. Take the old belts with you to match them up just in case.

RE: belts

Question: do marine belts officially need to be the non-static buildup type? ...to prevent static discharge explosions?

No opinions please...just references to the rules.

thanks "thedude" picked them up from Napa, they fit perfect!

I am pretty sure automotive V belts are fine. The belt goes about maybe 6 inches, at the max, before it hits another pulley, that is grounded.
Sorry, that was an educated guess, or an opinion.

Interesting comment on static. I searched the web and found NO topics on the difference. I also I went on Gates website and although they do have a marine section, they say nothing about low static or NON static marine belts.

IMO it is just an OEM thing. I have always purchased belts from Napa, Autozone and never had in issue.

About 10 years ago, I specified some machinery for a refinery and the belts on the compressors and fan coolers were anti-static. I've seen those requirements on other NEC Class 1, Division 2 areas.

As explosive as the engine & bilge can be....I was thinking static free would be good.

A few years ago I found the dimensions of a Quicksilver belt and matched them up to a Gates automotive number. Installed it and never looked back.

So, ....the question is....what makes a marine belt a marine belt?

Ditto on the OEM.

More guesses. I would think to prevent static electricity build up on a V-belt, it would have to conduce electricity to some degree.
I went and got a PCM belt for my boat, RO66001. Water pump, or alternator, I can't remember, but it is one of them.
I got my Fluke DVM. According to the Fluke meter, the belt has infinite resistance, even with the two probes very close to each other, both touching the belt, on any surface.

Guesses are okay for science...not for USCG, ABS, or DNV rules, etc.

(I guess) the issue is charge capacitance not resistance. In addition, the "perfect" volt meter would draw no power...but in fact the volt meter would discharge the belt in just a few milliseconds.

The situation is similar to rubbing a balloon on your head or dragging your feet along cold carpet in an arid climate.
A charge builds up, ....then "ouch" 10,000 volt discharge. That discharge would be enough energy to ignite a combustible gas mixture.

I'm not sure of a credible scenario of the belts discharging under the hood...so I'm feeling okay with regular old belts.

I still would like to know from Gates what makes a marine belt marine and if Rules requires a anti-static belt. Some research for another day.

I went to the Gates website and looked up the part number for the 5.7 PCM engine:

http://www.gates.com/part_locator/in...cation_id=3002

It came up with 3 part numbers for the 5.7 PCM marine engine, one of them being PN 7455. I looked up all three PN's that the site gave me and cross checked which vehicles they go to, it came up with a huge list of cars/trucks/vans for each of the 3 PN's.

This leads me to believe that the belts are exactly the same as automotive belts, at least accoring to the Gates database. So, according to the data base, Gates Marine Belt PN's 7455, 9400HD, and 9400 for the 5.7 PCM engine are the same belts used in many automotive applications. Let us know if anyone has come up with different findings.
