I could flip my 800hr motors for 20k and buy sub 100hr 2023s for 40k. Get that deal done and motors swapped in 3 days. Really getting hard to find someone down here that wants to crawl into a bilge. I inquired about getting the 330 MPIs in my 330ss converted to closed cooling. The most reasonable $/hr shop down here that I use wanted $6k for the job. A 496 might give you comparable hours and corrosion resistance as an outboard but those haven’t even been built in a decade? I agree those to me seem the best bang for the buck when reliability is the goal. Hang a pair on a 30 spectra cat and that would be a cheap fun ride. |

When you say sub 100hr 300's for 40K are you talking the new V8's? Is that with controls?

3x these gets you 3x318hp less than 90k. Weighs 1600lbs and turns 6400. No way twin 520s last longer than this setup or cost you less to service. 520s slower too. |

How many new sport boat Vees and cats are built with triple 300s though? When the 450Rs came out, the "old" Verado 400s in stock dropped to $40k new. Now that was great bang for your buck on a solid proven engine platform.
They were a great deal there at the end. Boat mechanics like the serviceability and durability of the L6. If you watch THT you’ll see guys flipping low hours L6 400s for the next couple years. Some guys just automatically repower every 2-3 years. |

Thank you for your post with the comparison. I was basing the price without ITS added and standard XR drive https://www.proboats.com/engines-for...California-US/

Seems old school going back to egg beaters no matter what the hp. Especially since they've eclipsed the cost of a decent hp I/O motors. Cost for maintenance these will not be any cheaper in the long run. |

Hogie,
My point is that the majority of the selling points for quad OB CCs are outright myths, offered up to make an upsell. Again, there’s no way you’re going to convince me that maintaining 4-5 OB is easier or cheaper than a couple of big IBs, and the upfront cost leaves plenty of room for maintaining the IBs down the road. There’s also no way they are more efficient. At the end of the day, HP means fuel. Period. Thanks. Brad. Also, in regards to maintenance, I can assure you that I could change the oil, change the spark plugs and pencil coils, and even swap 4 starters faster on a quad Verado boat than you could do a tune-up on a side by side sterndrive boat. And I could do it from a step ladder. |
I don't have a good rational argument here as for the true fuel economy numbers, but I will tell you that a friend I run with has a 35 statement CC with 400s (non-R) on it and his fuel burn on those at WOT matches my more powerful big blocks. That's just reading GPH recorded off the dang Mercury software so not sure if its accurate, or even a viable argument. Our boats weigh similar, but his hull is wider and less efficient for sure. Its a real non-valid comparison. Still....we are both about 86 GPH at WOT.....and that's 400s. vs modern 540s. His boat does carry a lot more fuel, so on water weight is probably off by 1000 lb also
Something also to mention. 86mph and me getting it as hard as I can....86 GPH. Pull the sticks back just a tickle and run 80-81 and it drops 20 GPH fuel burn. |
