Intermittent Duty (INT)
This power rating is intended for intermittent use in variable load applications where full power is limited to two hours out of every eight hours of operation. Also, reduced power operation must be at or below cruise speed (rpm). Cruise speed (rpm) is dependent on the engine rated speed (rpm):

Sea Vee builds a great boat. IMO the best center console, congrats on the build! Should be a kitefishing machine!

I don't know if this true or untrue or how that relates to hours but that is the way he explained it to me.
Lets hope that the 40,000 is a little conservative. If you cruise at rated cruise rpm's on that engine you should be around 14gph. Gives a life expectancy of less than 3000hrs. I run a pair of derated (330hp) 5.9's and they still run like new after 4000hrs, but I mostly troll for game fish and hence they spend maybe 85%+ of their hours burning 2gph each. I do expect to achieve 8000hrs+ before rebuilding, but probably only get through 20,000 - 25,000 gallons due to my usage pattern. If I was running them at cruise all the time I would have been thinking 4000 - 5000hrs before rebuilding, which for me would be pretty close to the 40,000 gallons you were told. I am pretty conscious of the effect of fuel burn on my engine life expectancy, so keep that in my mind when planning trips. If I can do a 14hour day trolling from A to B instead of a 5 or 6 hour run, I will often build that into my trip plans. Do twice the engine hours, but use half the fuel and hence it halves the wear on the engines as well as saving on fuel costs.

I have talked to several guys from Cummins and they have given me better numbers than that so I guess the truth is in the middle somewhere. We will see. Glad to hear your motors are running well.

Ducer is just aft of where the shaft exits the boat. It's a 2kw.

Nice boat, I like that you didn't skimp on the little things like the Hyd. ram on the hatch SS not plastic or tin, I can't believe the price of some of the SS Fasteners, my guys think it's cheaper to throw away than to pay them to sort and restock... Until they have to buy them... I've run Yanmar, Volvo, & Cummins. Cummins, was the best. Heaviest too.

This pic shows more of the system...


Single high speed water pickup (via a true thru-bolted bronze seacock in the center of the above pic, which you don't see on other so-called "high end" boats) feeds the sea chest that you see there with the clear lexan lid. The chest stays full of water, and the pumps inside therefore stay fully primed and cooled. They last MUCH longer than standard bait pumps, and there is not a bunch of exposed plumbing running all thru the bilge that can sink the boat when it fails. Notice that I said WHEN, and not if. The sea chest design here will give much more reliability in terms of pump life as well as thru-hull "security." Only one water pickup for the boat despite being loaded with raw water accessories and 300 gallons of livewell. If lucky would post a pic of the inside of the chest, I would greatly appreciate it. I am modeling a smaller version of sea vee's design for my own sea chest for my Mako that I'm redoing in fact. This one in lucky's boat is being done right. Notice that it is a nice stainless (right?) chest with neoprene gasket and full flange for the lid. Also notice that there are marelon valves for the outlets giving insulation between the bronze fittings and stainless body of the chest.

Extremely nice setup, that most would not invest in nor appreciate. Fits perfectly with the rest of the mindset and approach I see in this build. Spending the money where it really counts and not on useless BS. Just like the REAL sea cock and valve for the raw water pick up rather than a POS ball valve that costs 1/4 as much, you've also got bronze shut off valves on your drain thru hulls since they're below the waterline. I am telling you, this boat is being done right instead of simply "like the rest of the industry does it."

Boat will be incredible not just to own and use but also to maintain. What a dream. You will be right to be proud of her.

Thank you for sharing.

just curious. I hear people mention a prop pocket. I understand it would give the boat shallower draft but would it negatively affect fuel burn and/or top speed?

Thanks!! Is there a ball valve/ shutoff on the inline on thru-hull bronze seacock?? I can't tell from the photo. Is there a way if/when the chest should fail that you can stop the flow going to the chest?

Yes, on the seacock in the center of the pic, there is a shut off handle sticking straight up towards the camera. It has a white rubber sleeve on it if you look closely. Here is a pic of the sea cock going into my boat. Smaller version of lucky's.

Lucky's setup only has about 8-10" of hose that could ever fail on him- and no turns or stress points on it. If the hose or any portion of the "over built" sea chest were to ever fail, then he could easily shut off his seacock valve. Like I said, done absolutely right- and with low maintenance and long-term durability/security in mind!

Sea Vee does it right!! That Seachest is sooo much nicer than the others out there.

Phin you have an eye for details. Everything you are saying is correct. I will try to take a picture of the inside of the chest. I tried to lay out things in a way where those things that would need constant attention like filters, thru hulls, and electrical would be easily at hand and things like wash down pumps which you replace every couple of years were put into corners that would not be advantageous for constant tinkering. Certain things had to go in certain areas like the wash down tank.

Sal I agree with you. After walking the show I can certainly see the difference. I just won't name names because I don't want to start any trash talking since this is about a boat build.

ITMan I have seen SeaVee have to buy a certain part from a manufacture and actually take all the fasteners out of item and throw them away because they did not think they were up to snuff and replace them with their stainless steel.

Ok, you have gone this far.... Are you going to put an ac compressor on that motor? Ac at the helm for all those thousands of hours on the water?.. That is the only thing from my wish list that I haven't seen go in this build.

No sorry brother I'm trying to keep it simple with as little possible to break. Although, I will confess I did think about putting a hi-pressure wash down pump like you see on the commercial lobster boats that they use to clean the traps.

X2, many vendors use Home Depot type PVC valves.

What can of scheduled maintenance is required for this engine? Will you do it yourself while the boat is in the water?

the oil change interval is 500 hrs but I will not go that long. the transmission is first 50hrs and then every 300. Belts and filters every time I change the oil.

Here are some more updated pics. Boat is going nicely. I just wanted to show some details. Things like backing plates on the rod holders.
