Default gas or diesel express

Hello, I am looking at buying a Luhrs 320 express style fishing boat in the $20-$50K range. I have found them with gas and diesel. Is this too big of a boat for gas? What kind of longevity comes with gas on a boat this size? I would prefer to have diesels, but the maintenance costs and potential costs of rebuild is making me shy away. I am new to THT and I appreciate any input. Thanks

I looked at a couple of those boats. In that price range your probably looking at gas engines. It’s not too big for gas and as far as longevity it really depends on how they were maintained and that goes for both gas and diesel. A well maintained gas boat will last a long time and a poorly maintained diesel may not last long without major repairs/maintenance. I wouldn’t be afraid to buy a gas boat. I bought a gas Wellcraft 330 Coastal that was extremely well maintained and have been very happy with the engines.

All that said it also comes down to what you want to do with the boat. My biggest complaint about my boat with gas engines is the fuel burn and range but we fish offshore and the range is important to me.

I have found them in gas and diesel in that price range. I want to use it to fish and cruise mostly local. It's going to be my man cave! lol I think the Luhrs 320 has like a 340gal fuel tank. What kind of fuel burn and range do you have with your gas boat? Thank you for your input!!

“Too big for gas”? Not at all.
Diesel “expensive to rebuild”, realistically how much do you plan to use the boat and how long do you plan to keep her?
If you plan on typical pleasure use and find one with gas for $10k or so less then that $10k will go a long way in covering the extra fuel cost of gas.
Gas will probably be smoother and quieter.
I’m not suggesting one or the other, just some different things to consider.
Yes, diesel is nice and certainly has its pluses too. There is a reason they offered both. Neither one is “best” for everyone.

go with Diesel. Find one with rebuildable/sleeved engines like a Cummins. Diesel has higher upfront cost but they help with longevity, resale value, fuel economy, and safety (fumes).

Parts do cost more...

If you're getting the same boat at same price for diesel or gas, the diesel is probably trash because it should be much more expensive than its gas counterpart.

Also, if you aren't handy and willing/able to do your own work, be sure you have a bunch set aside for maintenance/repair bills.

For range on that boat I would calculate 1/2 mpg for gas and 3/4 mpg for diesel. You will do better than that, but if it gets really sloppy and you are heavily loaded you'll want to be on the safe side. If the boat has, or you are thinking of adding a generator, go for a diesel one. If it's a gas boat, then you'll need a smaller separate fuel tank. I'm sure there are people on here that will refute this, but I'm not a fan of gas generators due to CO concerns, especially if you plan on sleeping with it running.

I would shy away from diesels in that price range. When things go wrong with a diesel repairs get expensive very fast.
Also as mentioned above, most diesels used in small boats are not sleeved and are not easily rebuilt but rather replaced.
A remanufactured Cummins 6BT would run at least $30,000 vs a gasser at $6k

For your use I would go with gassers.
Amazing what express and sportfish boats are selling for in the center console revolution.

Depends on your use, is range a factor? If so you will probably get more range out of the diesels.

That is kind of my thought. But was worried boat may be underpowered with gas. Hell, I could repower the boat with gas for what it would cost to do turbo and aftercooler service. lol
I am looking at ones with generators and have questioned the safety of gas because of CO. My thought is put multiple CO detectors in the cabin?

I think the boats I have looked at have 340gal tanks. I don't think range will be a factor. Fishing grounds are 60 miles or so to the stream out of Charleston,SC. I have thought about taking her down to the Keys or Bahamas once every year or 2, but not sure that will ever happen. lol

very misleading #’s. A Reman Cummins comes complete , drop in from the factory and is certified. A $6k gas would only be a block from someone and then all used parts are bolted back on. To make it equal a new complete gas would be about $20k .

On a 340 gal tank you can take approx 10% off of that number for usable fuel. That leaves you approx 300 gal. With the gas I would estimate approx 150 mile range with full tank maybe slightly more depending on cruise speed.

I have a 37 footer in gas. Yes it costs way more to fuel up and consumes way more in fuel but one valve lash job or an intercooler replacement would eat up any savings from owning a diesel.

Here is one thought.
My 29 Blackfin with twin Cummins was a tank. Access to the motors was tough. The issue is that idling out of the canal with wind behind me pushed diesel exhaust into the boat. No issue for me but the Admiral was green in no time.

Not sure what the fear about diesel is....

The comparisons about rebuilds are totally inaccurate, along with the fact that a diesel will outlast a gas significantly.
The fear of the thousand hour service is every thousand hours....Most people don't even put 50hrs a year, let alone 100. Thats 10-15 years before you need to do it.
Between cost and efficiency of gas vs diesel, as we are today, you're looking at half of the fuel costs.
We all know engine life comes out of consumption of fuel, and how hard these engines are pushed. Keep in mine, a 32' heavy express is not a 25 foot CC, gas may move it, but with ALOT more effort than a diesel. In a like-for-like situation with similar maintenance, you're getting at least 3 gas rebuilds before you even need to worry about diesel, if not more.
Alot safer. No worry about running blowers for 5-10 minutes before turning on after fueling. No highly flammable noxious fumes all over. List goes on and on.

In my opinion, there is no comparison. If you want gas, go outboards. If you go inboards, go diesel. With that being said, if the diesel and gas are identical pricing, either the diesel is under priced or the gas is over priced. Should never be the case, make sure you get a quality mechanical surveyor.

All things considered I would hold out for a 32 with the 370 Cummins. Very efficient, should get over 1 nmpg.
I prefer not to have a gasoline boat. Have to remember to run the blowers, volatility of gas even when fueling etc.

I have a 30 Pursuit with twin Cummins 4BTA diesels. A friend has same boat with Mercury gassers. He hates it so much that he is looking for a set of running take out diesels to put in. My engine room is tight, no matter what engine is in there. V8s are just as wide as an inline diesel. He complained about his range with the gas engines. Go diesel, you will not regret it and you have better safety and better re-sale.

How often will you use the boat?
My diesel maintenance is $1700 every 2 years for an aftercooler service. I remove them, drive them to my mechanic and put them back on. Also, if you put a freshwater flush on the aftercoolers you can go a lot longer between aftercooler cleanings.
Zincs, oil, filters, impeller and a belt every year. Not too expensive.
My 32 weighs a lot more than the luhrs and is a deep V. She gets .80 nmpg.
I troll a lot and it sips fuel trolling.
Some weeks you could easily put 20 hours on the engines if you fish enough.
If you plan to use the boat a lot, the longevity of diesels and better fuel consumption will save you money.
Higher resale. No risk of explosive gasoline vapors.
The problem with diesel is they have to be maintained and not abused and most people dont maintain them and overprop them reducing the life of the motors.
