    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Your engine should not be hitting the limiter at full speed. If the engine is rated for 5220 RPM's and it's rated for 5000 RPMS then either the power package has the wrong propellers on it or the props are slipping. I would start with a prop and prop shaft inspection first. If the props are...

    My boat is being a boat . . .

    The codes mean the engine is either running richer than it should or it thinks it's running richer than it should. I would put the boat in the water, put fresh gas in it, and run the snot out of it and see if it clears up. If it duplicates make sure the engine is heating up and getting to full...

    V Drive trans oil analysis 1999 380 DA

    Glad to hear you are doing well. I have 2 houses, the main home and a rental. The storm put water in both houses. One insurance company has been good to deal with, the other not so much. All I can do is keep on trucking.

    V Drive trans oil analysis 1999 380 DA

    Hi Bill, I am doing well thanks, how are things on your end? I am down in SW FL where I have been for the last 10 years. I own a survey company and spend my days surveying boats and playing my part in processing boat insurance claims. I was ground zero for Hurricane Ian and have been busier...

    V Drive trans oil analysis 1999 380 DA

    I look at maybe 100 oil analysis samples every year. The short version of this is a 1 off oil sample really doesn't mean much unless it's showing water, potassium, or sodium, all of which indicate a saltwater leak. ' Oil analysis is used as a tool by fleets to measure engine wear over time so...

    api scan tool opinions?

    You didn't say what you were going to be working on. If you are going to be working on Mercury, Mercruiser and Volvo Diacom is the best you are going to get short of buying G3 and Vodia, which you can not get without a dealer license. The best part about diacom is the updates have always...

    api scan tool opinions?

    I've never heard of API, just had to google it myself. It looks similar to a Can-Doo. I use Diacom near daily. What engines are you going to be working on and what are you looking for your scan tool software to do for you?

    can someone let me know what fuse sizes?

    You should be fusing in accordance with the manufactures specifications for the component being fused. When new in the box, the blower bilge pump, wiper, horn ect would have had an owner's manual stating what size fuse to use. The issue with using a fuse of a higher rating on small electric...

    Purpose of material under fuel tank in aluminum boat?

    H-24 does not differentiate tank types in terms of supporting the tank. Tanks of all types must be fully supported. You should dig all that crap out to see if poultice corrosion is forming on the inside of the hull. Also, no need to shout. You are getting free help from a master tech.

    Purpose of material under fuel tank in aluminum boat?

    I'm not "trying to pick a fight". I am simply correcting misinformation. You said the paper is there to absorb vibration. That is not true.

    Purpose of material under fuel tank in aluminum boat?

    Couple of things.... 1. What you posted is out of date. 2. ABYC very much holds up in court. 3. ABYC does not come from USCG requirements. Here is the current version of 33CFR 183.550 -...

    Purpose of material under fuel tank in aluminum boat?

    ABYC H-24 states the entire fuel tank must be supported. IE the fuel tank should not be "floating". For example, if a fuel tank had brackets mounted to it, and the brackets were screwed into stringers, and the bottom of the tank wasn't touching the bottom of the boat (or anything else) that...

    Purpose of material under fuel tank in aluminum boat?

    Can you elaborate as to what you mean? ABYC H-24 is the authority on fuel tank installation. H-24 doesn't use the word vibration...... Fuel tanks are not only allowed to vibrate, but they are also allowed to move. They just can not move by more than 1/4 of 1 inch.

    Battery Options

    LiFePo4 is "safer" than Lithium Ion, but still not fool proof. They will still catch fire under the right circumstances. If they do catch fire, its a fire you can't put out. So if you go that route, either have a fire plan in place aboard the vessel or switch to lead acid or AGM.

    Crappy hose

    Okay I've seen that before. That is not ABYC, what you are reading is 40 CFR 1060.101, it's a code of federal regulation, not an ABYC standard. That table was simply created by somebody who had no idea what they were talking about. (Maybe it was Ed Sherman after a couple of scotches, but who...

    Any chance you can quote the ABYC standard that cites that?

    Understanding Moisture Readings on a Marine Survey?

    I'm a SAMS guy, I can tell you ACMS is a mail order organization, they do not have the reputation of SAMS or NAMS. "ABYC Certified Master Marine Technician" I am also an ABYC Certified Master Tech, there are NOT that many of us. If you want to PM me this person's name, I will be happy to check...

    Understanding Moisture Readings on a Marine Survey?

    Was your surveyor a SAMS guy? I use a moisture meter, but I don't list readings like that. Moisture meters give comparable readings, from 1 spot to the next spot, and from 1 brand of meter to the next meter. The numbers 20 or 40 or 80 don't even really mean anything. 20 Compared to what? 40...

    Blue smoke during warmup

    I would do the leakdown test next. The engines might only need a valve job.
