QSB 5.9 380 with 5000+ hours.

[Hiroki Toma]

Hi Captains
I am looking at a boat with twin QSB 5.9, 380hp boat with 5100 hours on them. Boat is 2005 and records show that 90% is trolling speed. I think they overhauled the turbos once. If the boat performs good reaching its rpm specification with no smoke and good reading on all gauges should I worry about the hours? I am planing to get the engine survey if everything goes right, but I figure to get some opinions here. thanks.

Well that’s when you know without any doubt that it was a very good boat!

Hiroki,

Check out this thread that I started a little while back. Are you looking at a Tiara 3600 Open? Check out the back and forth I had with the forum. If it is not the same boat then maybe this thread is of value to you. I ultimately passed on the boat for non-technical reasons but it was an informative discussion just the same.

From reading your post, it is the same boat. I went down to Marathon Fl. to see the boat. The boat was spotless, engine room was very clean and the mechanic/engineer told me everything he has done on the boat. They lowered the boat into the water, both engines started right up, no smoke and both engines purred like a kitten. During negotiation, owner changed his mind about selling the boat. oh well.

Thanks

Hey Gents
Thanks for the replies. During negotiation, the owner has changed his mind to sell the boat.
I am on to the next boat which has 700hrs on a 2007 QSB 5.9 355hs engines. I am having the boat survey and have the engines and generator inspected by a Cummins Sales and Service technician. Thanks gents.

Total fuel used

Correct me if I am wrong but shouldn’t the ECM record total fuel used? This will tell you how hard the engines have been used overall

Looks familiar…….

I work on a boat with those same engines. The ones I work on have about 8k hours and it runs like a Top. I would post the pictures and give sea trial results. What is involved with the engine survey? To me if you have the service records, that and a seatrial will tell you the most

What exact records are you referring to and what other records are available? Maintenance? A chart of GPH vs RPM would be quite useful. Do you have the serial numbers to post?

For me to comment with some substance, I want to see really good pictures of the engines, as installed in the vessel, from all angles and perspectives……….

Picture this–I am on the boat doing a survey.. Put my eyes there and if you do it right, I will tell you by far more than your survey dollars will tell you.. And, that’s for FREE..
