Nortech builds a 390 with quad 400's. Similar hp. Motors around 30k each. 120k total. Seems like easy decision for me. By the way boat ran 100mph. I have seatrialed many Intrepid's with 7 power. They are also louder than the 400r also. However there seems to be the cool factor of owing a boat with them as not everybody has them. Seven seems to be happy as Sydways pointed out, putting 3 or 4 on the back of the BIG CC's coming out these days and pushing those heavy beast to pretty decent speeds that they were not seeing before. |

I just have a hard time wrapping my brain around putting that much weight and torque on a transom and having it stay in one piece,,,,

Yes, it was a rigging issue and/or metal failure.
But it illustrates the point of why the Seven Marine motors we developed. Comparable power/performance with less infrastructure. Sometimes 20% less. Sometimes 33% less. More details from another site: The clamp bracket did not break......... and it happened at 40 MPH in calm waters..... we hauled it out and supported the motor until the guys from Midnight came to take it away...... The motor was ok,,,,, no water ingestion, infact there was no visible damage. It did damage the motor next to it with it's prop... took a chunck out of the cav plate. The motor was through bolted to a plate to get it higher and the plate had studs welded to it to attach it to the transom. there were no through bolts directly holding the motor onto the transom. The studs sheared right at the plate and the motor was left dangling off one remaining stud and the tie-bar. |

What about fuel consumption on these boats? Similar HP either 3 triple 7 and 4 400r's!!!!! I would have to think having one less engine would burn less fuel, and with guys putting 1000hrs on a boat that could add up.

I am not sure if you have the cash for something like that if you really care about cost of fuel.
Still would be interesting to see some data on fuel consumption of quad Verado vs triple Sevens at the same speeds on the same hull. |
I saw a quad verado Midnight Express at the place that serviced my boat. Mechanic is Merc Platinum Certified, 30+ years in high performance. I was in awe of the quad power boat and his reply was priceless.........he said look at the trouble you are having keeping two I/O's going, why would you want to tackle 4 motors on a single boat!
BTW the 39 ME was in because the outside motors were eating lower units......if owner was running it hard, it the outside motor would run dry in hard turns. :evilb: |
