I have a few thoughts. As jeffk said, some of this is simple stuff you can do to save a ton of money. Others, you can also do but it will cost some $$. For instance: Easy / save $$ items: bilge pump/float...change them out. Buy at West Marine or even off Amazon to save $$ clean the mold off the a/c return vent. compressor will be more complex, but look for codes and do your research. Might be simple fix. rear storage hatch...find part numbers and order new latch engine hatch...takes an hour? Have somebody assist the hatch by lifting up on it while actuating the motor. This will prevent the overload situation and breaker popping. Batteries probably weak. If you're hooked up to shore power and charger is running, it might not pop the breaker and open faster due to the additional voltage/current (ask me how I know) water system can be sanitized screw holes can be reinforced Other items that are relatively easy but cost some $$: One fix for the gauges (including fuel) would be to eliminate all of them in favor of a VesselView system. These run off the diagnostic port on the motors and act as engine gateways as well. This eliminates most of the wiring harness that may be compromised. You would have to run a new cable from your diagnostic ports to the helm bypassing everything else. Add a NMEA 2000 network to network everything including the new radio remotes (and head unit) that you can swap out for a very nice upgrade. GPS and VHF will likely need to be replaced due to being out in direct sunlight and not working. These can also be added to the NMEA 2000 network for added capability. A good mechanic can get your generator running. Likely electrical (relay, sensor, etc.) I can't help with some of the other issues, but everything above should only run you $3k or so if you do most of the work. The shore power issue may be your biggest issue....don't mess with that. Get it repaired correctly. You'll end up with a much upgraded vessel. Good luck!

Good point. Here's a link to some details on this topic. Supposedly the product represented here is safe for coral. https://www.rawelementsusa.com/pages/environmental-impact

What is this "test button"? Is it on the injector itself, or are you talking about a piece of diagnostic equipment? I do get 43psi at "key on".

Thanks. Is there any way to test the coil or the crank position sensor? How about the injector test? Pigtail? Merc hand held? Never heard of them.

Last weekend I replaced cap, rotor, plugs, wires, and fuel filter. No better. This past weekend we hooked up a pressure gauge and got normal readings while the engine was "popping". The plugs I removed last weekend all look good except a few looked like they might have been running a little lean (grey color...not more "burnt" like the others. They were only about 18 months old. Mechanic looked at them and agreed.

No popping in neutral. And after riding with my mechanic yesterday, we discovered it’s popping even above the original 3600-3900 band Where I heard it. So anything above about 3500 RPM under load will produce the popping.

Fuel pressure is good. No obvious vacuum leaks. Leaning toward a bad tank of fuel. Going to install a fuel/water separator filter, maybe hook up a fresh outboard tank of fuel and see if it doesn’t clear up. If not, then next steps will be injector cleaning.

Welcome back! And very happy you're doing better! Beautiful pics, too. To continued healing and health!

There's a lot of talk over on the Chaparral facebook page about putting together a Chap Bahamas trip. That group sounding like the Bimini run might be their preference.

Thanks! I ordered a pressure regulator today just in case. If not, I can just send it back. Amazon!

Thanks for the link. That's exactly the first thing we're doing on Saturday. Checking the fuel pressure. Praying that's it!

Good advice, thanks! I'll show this to my mechanic as it's a bit above my head. I don't have a code reader, but I have a Vesselview 7 and it's not showing anything. I suspect it should show any codes thrown, but I have not seen one yet. After all, it runs off the diagnostics port.

No it was the old plugs that were looking bad to me. Others say they didn’t look bad at all. Shows what I know!

Replaced all the plugs and wires. Took her out and same symptoms. Starting to think maybe fuel related or maybe valves sticking. I just don’t know. Waiting for my mechanic to call me back and likely put him to work.

Four plugs replaced on starboard side. Man they look bad!!! Changed the wires too. Resting before I tackle the port side plugs and wires.
