Looking at a new (20012 boat) with theses motors, comments,thoughts ?
 
No personal experience with them yet, but I've been shopping for a new (to me) boat for almost a year (a somewhat discouraging, but educational experience). I'm looking in the 380-420 Sundancer range. The 380's & 390's are mostly gassers (which I am fine with in that size), but after looking around a lot I'm seriously thinking of adding a little more to the budget, and going for a 410 or 420. Most of the 410's have Cats. My only hesitation on those is because I get a lot of mixed reviews on Cats, but overwhelmingly positive reviews for Cummins.
DISCLAIMER: I'm not making a judgement about Cats. Just sharing opinions I've found while researching my next boat.
I've spoken to two diesel mechanics about the choice and while neither trashed Cats, both of them independently strongly endorsed Cummins.
I've got to go a little newer (even bigger budget)and get in to the 420 to get Cummins. With one kid in a very expensive private college, and another kid going to start looking at colleges next Spring, I just have to wrap me head around the bigger budget.
 
By all reviews excellent engines based on long history high production 5.9l Cummins.

Cummins support and parts are first rate.

How big and heavy is the boat?
 
The aftercoolers will be ready for service
 
So what is up with aftercoolers and service for such, is it hours on the motor this needs to be done?
 
I love my Cummins. Intercooler should be done every 3-5 years. It's an easy DIY job. Go to biodiesel and look for the o ring kit.

What boat are you looking at?
 
Coolers need to be resealed to make sure no corrosion has caused leaking. a good idea on any engine where sea water and intake air are in close proximity. Not a big deal just a maintenance issue. I only buy my parts, especially the cooler O rings from seaboard marine. they always get me the correct parts. The local Cummins truck shop many not. If you buy it the Cpl number and serial number on the engines is the key to getting the exact correct part for your build.

After long experience with Cummins C model I would not hesitate to buy those engines.

As with any diesel make sure they arent too overloaded at sea trial.
 
The Cummins "C" series 8.3 engines do not share anything in common with the "B" series 5.9 series. The C engines are very robust and need little attention over time to perform well. With the 6B series it is important to avoid any overloading (overpropping) of the engine as well at attending to a few items quickly such as the raw water pumps, aftercoolers, CCV system, fuel coolers ,check the turbo etc.

I would never own a gas boat ever again!

Don't make fun of me, need to downsize, the Silverton 45C is awesome, but the beam and power requirements are crazy for my pond.

My uncle has the same model meridian his is a 2006 he's brought the boat from ny to fl a few times and loves the shallow draft of it.
 
In the event you're interested in feedback...

I've known many 391 owners and never one who didn't love their boat. It's a good coastal cruiser and while it may not take punishment as well as the Silverton, I'm guessing you avoid punishing conditions whenever possible rather than seeking them out. It's also boasts a terrific use of space which with the added length and beam make the accommodations feel much larger than most in its class, particularly the 36 DB in my opinion.

For what it's worth - and you've no doubt seen the listing - this is a very well cared for, nicely upgraded 391 I'm familiar with out near Riverhead owned by a passionate, meticulous boater: http://www.yachtworld.com/boats/200...92190/Aquebogue/NY/United-States#.V-aBKev3arV

That one is nice but for $80k more the other one is 5 years newer. I think the 2012 is cheap and the 2007 is high.
I know what Walter will say about the 2007 as he doesn't like the striped seats but that can be changed.

Either way I like the meridian.

The B and C dont share blocks but they do share simple design concepts, extensive knowledge and support network, inexpensive parts compared to others, high volume production and great reliability. they also share after coolers and raw water pumps that while different both require attention. neither likes overloading.
 
i m not sure how down sizing a few feet makes such a big difference.... Still two engines, one generator, same electronics, same air cons, same steering system, same time lectricsl system, pretty much same canvas and soft goods, same shore power cord and same number of lines.

IMHO - The engines are anything but similar. The C is installed in most any bus and coach applications as well as many street sweepers and other similar heavy machinery. The B series is found in recreational pickups and is better suited for that application. I have helped quite a few B series owners with their engines and found the parts costs to be fairly high on impellers, fuel coolers, aftercoolers, turbo's, injectors and most anything else we needed.
 
Hi smitty. Compared to Volvo prices?:D I always bought from seaboard ad got better pricing than the local Cummins shop.
