I moved the pins to match up with the Yacht Device explanation of what there wire is looking for. So Can low of the gateway to Can low of the tech wire which for me was Light Blue. It may not be light blue in your case. If not, you need to find out what wire does what.

Hi Yellow to ground Red - 12 volts White - Can High Light Blue - Can Low Purple - ignition Hope that works for you.

Its really the fumes. The water intake is generally below the boats so that should not be a problem. Also most have a flap to let the water out but not in.

I hate to say it. But any good boater should carry a knife on him. I have picked up lobster traps, small trap bouys under the surface. Even fishing lines. One storm I had to cut a boater free from his cleat.

As I mentioned "total of 450hp". So that's 225hp out of each engine. No supercharger.

You need the raw water pump running. Or its going to overheat.

I have a 2011 290 with 4.3L. Seams to have plenty of power for me. A total of 450hp. Gets right up on plane. Maybe it needs a tune-up. But are the fuel pumps making a high pitch noise. If yes, there could be failing. Mine did last year and after installing two new ones it got up on plane quicker.

Yep!

I have 3 house batteries. So yes.

I had almost the same problem with a boat I bought that was one year old. It only had 19hrs on it and I could not find the problem. A friend helped me and he looked at the impeller housing. It was all scored from sand! The last owner must have beached her and sucked it sand.

Yep!

Nothing wrong with that!! We need tools and parts when under way.

Yes, that does come in handy. I bought a portable VHF just for that reason. I use the fixed VHF to call them. The VHF has more power and the portable is a backup to the fixed unit.

I do have a closed system. But my 290 with twins is a 2011 model. Its been in salt since day one and it stays in the slip all reason. So far so good! So its now 8 years going on 9. So I think you can get a few more years out of it. I would wait before removing the manifolds at least two more maybe 3 years. If your going to remove them, than I would replace them.

Its is a great site!

Yep!

If you cross your lines on the stern and go from the cleats on the platform. You would be less likely to trip over the lines getting on or off the boat. I would rather have too many cleats than not enough. In a storm, I think someone else pointed this out too. I would not use them.

I thought this was good. It also makes it very east to adjust fender height. https://www.amazon.com/gp/product/B00NMX298I/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Yes, hot water!

They do make digital gauges that are NMEA2k that can interface with most engines. As in https://buy.garmin.com/en-US/US/p/126694 That can display almost any data.

Yep!

Have you looked to see where the spark plugs are on the genset? Is the room that tight? Spark plugs are one of the easiest things to replace. You might be able to do it yourself.

Disconnect your remotes one by one and see if the problem goes away. I bet thats the problem.

I did not care for Sea Dek ether. Plus they would not honor there own warranty.

I am not sure. I would download the instructions before I would buy it.
