Have Boat Questions? Ask a Boat Repair Expert.
I'm Jason, I'm one of the top experts here. I am also Volvo gas and diesel certified. Let me see if I can save you some time here. Do you have a scan tool for the engine?
Well, here is where you are at. And I'm giving you this as a freebie here, as a courtesy, and to save you some time.
You either need to buy a scan tool. Or hire a guy/bring it into a dealer where they have a scan tool. These are electronically controlled engines, with cam and crank sensors, a computor, and a host of other sensors. You can not fix these by taking a voltmeter and sticking it on certain color wires. All you can do with out a scan tool is check your fuses, and thats about it. Everything else has to be checked via the scan tool. Now if you want to buy a scan tool I can make a reccomendation if you still want to DIY it. They run about 400 bucks for a basic one, and you will need another 60 bucks in adaptors for it. But your not going to fix this without a scan tool. Not unless you throw a dart at the engine, the dart hits a sensor, you replace that sensor and end up being the luckiest man in the world.
I'm sorry the other guy wasted your time. Thats why I posted what i did as a freebie. I have a 2k dollar all aluminum laptop that you can throw across a concrete floor and it will still work. Loaded on that I have a few thousand bucks worth of diagnostic software, and adaptors to make it all work. I'm volvo certified, have a degree in marine technology, and even I can not fix it without my laptop.
If your planning on keeping the boat a few years, and your handy, the scan tool is the best thing you can buy. What you want to get is the Techmate by Rinda. Here is a link to it.
That tool will do everything my laptop does. the only downside to it is that it only displays 1 line of data at a time, so it is slower to work with. But it is still a full function scan tool. The scan tool runs 400 bucks. You order them through Rinda directly, just order it over the phone. You do not have to be a dealer to buy one. Rinda's phone number is(NNN) NNN-NNNN and here is a link to their contact page.
Now when you talk to the ladies on the phone, tell them you need the Techmate. And then ask them which adaptor you need for your engine. Just give them your engine model number and they will get you the correct adaptor for it.
PNW... Is that Pacific North West? Washinton state or Oregon.. that area?
Post back with any questions
I'm in SW Florida. It will be 95F here every day until october, then spring starts. And really thats boating season. We have the opposite problem down here. If you go out in the morning (and you have to) it is just to hot to say out past noon or 1. Then you have to worry about the thunderstorms in the afternoon. Our winter is really spring. When your winter is actually winter.
Either way, you are very welcome. Good luck with everything! And if you ever need me in the future, just pop my name in the question(Jason) and I will be sure to see it.
