I think it depends on how you use your boat also. If you slow cruise short distances I think gas is fine. If you travel long distances, like the Great Loop, go diesels.
Just found your channel. Have a 2000 Sea Ray 380 with CAT 3116 diesels. Have it at North East River Yacht Club in North East, MD. Plan on taking this boat places, so I ruled out gas engines in my search. Removed both engines and took them to T&S Marine in Crisfield MD, one for an overhaul and the other a full service. The torque of the diesels is great for moving the boat around at idle and just using the transmissions for steering.
Thanks for checking us out! Wow, so you removed diesel engines for overhaul? Or you mean 1000 hr service? Glad to hear running good now - we pretty much always dock with our gears. 380 is a great boat btw.. very similar to our 410DA!
@@MyBoatLife Bought the boat from the original owner. The starboard engine and generator had issues (boat priced accordingly) so pull the port engine while I was at it. Boat at Bay Boat Works in North East, MD. Removal and reinstall wasn't all that difficult.
I read that the rule of thumb is any boat 16,000 lbs or more better off with diesels. Although in Europe it's common to see 26 & 28' cruisers with diesels
Any boat over 40’ needs to be diesel for sure. The 8.1L and 8.2L gas engines made a 37’ to 40’ pretty appealing in gas. Those 454’s are not enough for anything over 36’, especially a heavy boat like SeaRay, Regal or Cruisers.
A straight six has one manifold but V8 has two oil changes are expensive on diesel but diesels last longer because they rev slower and propellers spin faster
Looking at a Regal 3880 now, gas and diesel. Of course diesel is the better option but when you boat 50 hours a year the extra purchase price of a diesel is hard to justify.
A few things to consider… less moving parts so less maintenance, more power for bigger boat (tho 38 might be ok) and resale value - diesel’s longer life maintains value on market. Good luck.. that’s an awesome boat either way and thanks for watching!!
That stale gas is a constant issue for something that sits and absorbs moisture. Diesel can be stored with Biocide for decades with no degradation of the fuel oil.
Looking at a 2000 sundancer with 2 cats for the next boat !! we currently have 280 Sundancer with the 4.3. Two months in. And ready for something bigger 🤦🏻♂️😂😂
Where im from it would be unthinkable to have a petrol inboard. But the main reason comes down to cost of fuel. Petrol is a good 50% more expensive than diesel. That in combination with higher fuel burn makes them quite unfavourable. The rule of thumb here is that if you use your boat less than 40 hours a year, petrol ends up cheaper due to lower maintenance costs and price of purchase. But pretty much every petrol boat would be an outboard.
Few thoughts… With shaft drives, the engines are mounted further forward which makes the boat better balanced, quicker to plane, and usually a roomier engine access. With V drives, the engines are crammed near the back of the boat which makes the boat back heavy, harder to get on plane. That said, V drives leave more room in the boat for living space.

Sure use case always a factor, for us efficiency is more important than speed, gas version of our 41 ft boat is gas guzzler

That sounds about right - too many gas engine bigger boats are underpowered. Diesel is definitely more common in Europe.
Oh yes, the bigger the boat the more dramatic the fuel difference. 30-40% is normal but you could see a 100% or more difference in larger boats.

💯 agree!! 👏👏

👍 yep
Diesel for sure. I've had both and also had 502's on a 41 foot boat and while it ran good, it also sucked down fuel like no other.
literally a gas guzzler! 😭
@@MyBoatLifeyes and was slower than my 46 footer with cummins.
Anything with a inboard enclosed should be diesels, petrol is just to dangerous fumes ect make boat go bang
yeah go bang is not good 😩

50 hrs a yr, maybe join a rental club.
@@jimpatrick8021sure, for a CC or bow rider, that's not what we are looking at.

We love our CATS and the 410 is a great boat for space & performance. Good luck on your search!!
Diesel. On a big boat your diesels should go 10K hours before you do anything to them aside regular maintenance.
Yeah definitely thousands!! 👍

I think no that all makes a lot of sense! 👍
No need for blower before starting
Exactly!! 👍
Typical gas engines use approximately 30 - 40% more fuel consumption at cruise than a comparable diesel. The fuel consumption isn't even close
Agree diesels way more efficient
Any thoughts on V Drives vs Shaft Drives?

safer diesel over gas. cant blow up your boat with diesels no explosive fumes
exactly another big reason we like diesels better
Ya, Terima Kasih, Sama-Sama,
