Maybe ? Adjust the idle to the the best "seat of your pants" overall feel-- Lower or higher may help. Seaboard Marine Inc.

MHP vs. BHP--Your choice--all the same--Think of ii like 25.4mm = 1" Common older Cummins mechanical engines: 370 Diamond= 355 BHP / 370 Cummins MHP 330 Diamond = 315 BHP / 330 Cummins MHP 220 Diamond= 210 BHP / 220 Cummins MHP 450 Diamond = 430 BHP = 450 Cummins MHP The reason I...

SMX Multi-Stage Filtration Systems Just to understand the basics of what we offer as to a Marine filtration product: All of the filters we use are based on Fleetguard products as we deem them as the highest quality available, the latest technology around, competitively priced, and readily...

Brain, Like many products, not every market is gone after by the manufacturer. You could take the product, repackage and put "marine" all over it, do a few tests and triple the $$..It's that easy.. That does not make it any better, only way more expensive.. 3M 5200 is a great product, but the...

DC power Distribution The attached DC Power distribution diagram is our preferred way with a twin engine vessel & one generator. Of course there are variations but the general idea here is if one system goes poo-poo, it does not affect the other.. Key points are you always know the battery...

Let's try this to understand my thinking process differently............. If you have an engine that requires electrical power to keep it running (any diesel that is "energize to run", why would you want any other electrical system on the boat to be part of that, or what I typically say, "talk...

Is your engine "energize to run" ??.. That one question answers all if you have a diesel and one of the reasons you have one is "reliability" .. Just ask Rudolf if you do not understand what I am coming form.. Tony

Extremely high quality & designed & built to the highest specs available in those days, just like Allison and many older Twin Disc gears.. But like everything, including us, eventually all life comes to an end.....Keep them clean , dry & rust free on the outside, keep the oil clean in the...

Send it to me direct the highest resolution you have tony@sbmar.com

I do not know if this helps, but for well over 20 years, we have been using moisture cured polyurethane sealants from TREMCO and will never look back.. I learned the science behind them & avoided all the "marine hype" and associated "marine costs" about what they are all about way back.. As...

Send me the pics direct in HIGH RES------Can you "mark the crack? ------- tony@sbmar.com Stand back farther so I can see the entire pump

Some good pictures would help!

Not to discount all of the tests I have seen like this, but none of them take into account "real ocean conditions".........................Add a light average 2-3 ft head seas and 10-15 Kts of wind and the numbers would drop at a least 25% over a 24 hour run.. Put some nasty weather (up or...

Answer these questions: 1) Your coolant temp after you have been running for at least 1 hour--Cruise RPM above 1600 RPM, and at idle or very low RPM's.. 2) Total hours since new? 3) You said you had the injectors rebuilt----Can you give me any accurate details and to what that required or...

Never seen such an oil pan on any QB 5.9 Marine engine. Send me a good pic and an engine serial. Tony

Add this much overlooked point-------------oil temps really need to get above 200F as soon as possible to free the oil of excess moisture.. If running slow for hours on end, it's always best to get the engine up to a high cruise HP load so the oil temp rises for a few minutes at the very least...

My screw up--I got you and "William R" mixed up.. Too many things.. Sorry

If these are high wattage coolant immersion heaters, then I would be very cautious about leaving them plugged in all the time regardless of a thermostat or timer, and especially so if "original from decades ago".. I went that route up to about 10-12 yrs ago and after seeing so many issues with...

What exact kind of block heaters do you have? Tony

Once you are in gear, that is way better than at the dock in neutral. Plus, you are going on a "trip"..

Lou, you are missing what I am saying.. I did not say anything about idling your diesel once it gets up to operating temp after RUNNING under loaded conditions ( LIKE GOING ON A TRIP).. What I am saying is to not run it at an idle ( or even above an idle) when it is not up to full operating...

Since I posted, I think most of this has been sorted out based on your answers to questions 1,2, & 3………………….This is where you are – Your operation is really bringing on your own issues.. 1) Quit trying to warm your boat up at the dock.. Do all your prelims before you start the engine.. Maybe a...

Bill, I've been watching this & so far all of the questions have be right.. But let's take a deep breath and start fresh although I may cover what has already been asked but maybe in a different way so I can get a better feel for what is going on…………………..OK?? 1) Current operation.. Do you try...

Service it right and you are good for 2 yrs in saltwater.. If in fresh water, probably 4-5 yrs..Remember, it has nothing to to with engine hours--It's all about "Marine Age"
