Truly Blessed IV

Engines
MAN CRM 900s
When we bought Truly Blessed II in February 06 the Cummins had 107 hours on them; the Onan 9MDKAV generator had 89 hours. We are the second owners of the boat. The original owner bought it new in the Spring of '04 from the SR dealer in Virginia Beach, ran the baot for the 04 season, then traded it in in the Spring of 05. The boat sat at the Tiara Dealer who took it on trade until we bought her.

So--393 hours later, we have had fairly good luck, with the exception of errant ragbotes who have backed into us, or have had their floating bird poop collectors break loose in storms and ding up our gelcoat. Little stuff. Thankfully, nobody has ever been injured aboard, (even Gary has been on my boat without injuring himself)

The boat has never failed to get us home, even when the Chesapeake gets feisty. With the exception of new thermostats and a starter on the starboard engine which I screwed up myself, the Cummins C Series have been remarkably reliable workhorses. We have had as many as 14 adults and kids on the boat and even with that load, we required no tabs to get on plane.

What would I change? I would really like dual racor 900 MAs for each engine, like the QSM 11 equipped boats have. I'd like the generator racor placed such that it is easier to get to. I'd like 6" more of leg room at the companion helm seat. Otherwise, I am pretty happy with the boat. 85 hours on the mains this year, so far. I expect we will hit 140 or so before Mr. Shrink Wrap shows up in November with his propane torch to wrap her up for winter.

Skip,

You have no idea how lucky you are to have the mechanical diesels instead of the electronic diesels.
 
We surpassed 500 burgers cooked on the grill on the boat today...

(We were at anchor... hence lack of PFD and being on the bow...)

(Not my kid... and couldn't swim worth a poop... kept the PFD on)

That's a lot of hours Skip... beats the hell out of sitting at home with the kids playing XBox.

Let the red balls start.

The mechanical diesels in my 03 420 were absolutely problem free after about 900 hours. I wish I could say the same about the common rail engines.
 
Mostly fuel delivery problems. To make things worse, there was a recall that required a factory tech to repair and there is nobody around here that could do the work. I was out of boating for about 3 weeks while waiting for a qualified tech to fly in to do the work. Then there was the problem with the "timing"? of the injectors that was causing way too much black smoke. Then something about a fuel rail that vibrated loose.
Like most people who only remember the positive experiences and forget the negative experiences from the past, I miss my older boats.
 
OK... but that sounds like an "engine model problem" and not an "electronics" problem...

The issues I've had with my engines have had nothing to do with the electronics. That part of my diesel world works great... no smoke... quiet....

Now if they could just stop bolts from coming loose.
 
If I am reading the repair invoice correctly, the two unrelated problems that were repaired at different times were due to the electronics side of the engine package. The black smoke was repaired by a reprogramming of the computer sensors that are sensitive to (atmosphere temp/humidity)??? I think I am translating it correctly. I am going from memory but the injector timing issue was something that was a known problem not long after the engines were issued to SEA RAY in the summer of 2005. Not a big deal I guess, but definitely problems that cost me time off the water. During the same time period, my dealer was in the process of buying back a 44 sb from its owner with 10 hours on it because they could not diagnose the black smoke problem in a timely manor. The boat owner had owned the boat for 3 months and only put 10 hours on it. I was told by the factory tech that did my repair that that boat had the same problem as mine. I just gets old having problems that take so long to get fixed.
 
Dominic.........have you or Frank H. had anything vibrate loose on your engines? I haven't.

Should we feel left out?

And I'm sorry, I'm just not a fan of the early adopter aproach to electronic engine controls. Marine engines are the next to last place we should employ elecetronic engine controls. In a car or truck, you can pull over and wait for the Cummins guy. What do you do when you are 100 miles off shore?
 
Wait for the Sea Tow guy. No pulling over required. The Sea Tow guys are nice. I remember them well from my stern drive days. Glad I don't have those things anymore. Watched a 270DA get towed into the marina this weekend. The tow boat driver was very good.

Best regards,
Frank C
 
Way to go SKIP... Fuel prices had us curtail our trips some...

Im with yea 100% on the changes ... I blew a fuse on my bowthruster I couldnt reach the damn thing. One of my buddies had to do it .. ( directly behind the turbo )

I'm happy to see you've put some 'quality' time out on the water this season. I'm even more impressed that you still plan another 55 hours before the season is over.

I've only got about 50 hours so far and I'll be lucky/happy to get another 25-30. I'll put 10 or so hours this coming weekend to Cape May and back, and then maybe one more Atlantic City trip (6 hours total) in September. Then after that, just some tootling around and maybe dinner two or three times by boat before the winter blankets go on.
 
Dom,
I don't know what we would do on the weekends if we were not out running the boat.
We are blessed to be close to a lot of good destinations. As an example, this Saturday we are running north on the Potomac to Old Town Alexandria City Marina, where friends will join us aboard for beverages, then on to dinner in Old Town. That is about a 1.5 hour run each way, so not a lot of fuel $$. I will pass 100 hours for the season over Labor Day, heading south on the river to linkup with Gary and CJ. All good. We did 165 hours last year. We won't see that this year. Too busy at work..but we still run the boat just about every weekend.

Now if I could just train my 4 year old to run the Porter Cable....

Skip,

That is awesome. Just make sure your insurance is up to date, before Gary gets on again.
