Just in case you don't think about doing routine maintenance

I had been putting this off. Changed plugs to begin with, but this is what I saw as I dug deeper.

I replaced with MSD 8017 cap and rotor.

When was the last time you replaced it?

How do you like your Yeti? It was a good gift for me.

I've just acquired the boat in February. No telling about the prior owner. The Yeti is hands down, the greatest thing ever! Got mine as a gift as well. It's been put to good use, for sure!

[trayson]

Me too.

Boat was intermittently running like crap. coil wire had some corrosion too and replaced the plug wires and my boat runs 100% better.

When I purchased my 07 years ago, that was the first thing I changed out. All of it, wires included.

Followed by the fuel filter. I tried to burn all the gas out of it. I use non-ethol now.

Then oil changes in the motor and vdrive

Looking to do those in the off season. Dang V-drive is loosing oil too. Not sure where that is going. It's gone through a pint since Feburary, and only about 60 or so hours.

I just went through this as well, was discussing it in another thread. My cap was barely corroded, but intermittently was missing. I changed plugs too, but with only 170 hours, I can't imagine it was the plugs. I actually just cleaned up the cap and rotor a little, and it runs good again. If problem returns in the near future, I guess I will replace. How much was your cap and rotor?

[Plum Nauti]

About $60 off amazon

I had to take whatever my local auto parts store had in stock. I paid $30 for the cap/rotor together.

[jaywidhalm]

Crazy! The boat service shop quoted me like $90! Go figure.

[Plum Nauti]

Oh, the Indmar factory parts are $$$. And truth be know, it's probably the $30 set with a sticker on it.

[Plum Nauti]

I did get a factory set of wires. Fit to a T
17676

[jaywidhalm]

I read on line that they recommend changing these out at 30,000 miles in vehicles for this motor. Not sure what that equates to in boat hours, but that's more regular than I expected. Good to know it doesn't have to be $100 a pop!

[trayson]

I tried to get some random 350 plug wires from the auto parts store, and they wouldn't work for me. with the 340 CAT engine, there is really tight clearance at the distrib cap to the intake manifold, so no way straight ends would have worked on the starboard side of the engine. And the coil wire is really short. The routing is also different on auto vs boat, so I wanted to be sure I had the required length of wire. Yeah, it wasn't cheap, but it was nice that they were all numbered and clipped together and the optimal length.

Some things you can't skimp on. Glad to know its not an arm and leg to be able to keep the ignition system in check.
