More dumb Detroit questions

[rwappleton]

In what is beginning to look like a never ending search for a decent boat (At any price other than new). I have found a 1979 43 DC with what appear to have 6-71 TI's. My question is what HP rating would they be? Neither broker or Owner know? Also hour meters have 2800 showing on both motors and again everyone assumes it's correct. If so how much more would you expect assuming they have not been run WOT most of the time? The boat appears un-molested pretty much. It's going to need hoses and other normal maintenance

Get a survey and you will get accurate answers. Naturals are 310 hp. Last 10k hours or more if well maintained. High hp like 475the will last about 3-5k if run easy.

 

[captddis]

most likely 390 shaft hp. 410 brake.

I think 671 TIs are 410-450hp, depending on the turbos, injectors, and who marinized the engines.

2800 hrs on the dials is getting pretty close to the max life before rebuild for the TIs unless they were run at displacement speed like the N/As. The N/As can go for thousands of hours.

A good Detroit Tech can bore scope the engines and get a good idea of the condition and remaining life of the engines.

I would not be afraid of any 671ti if they surveyed well. 4000-5000+hrs is not unusual on those before overhaul. And as captddis said, those are most likely 410hp.

All good answers above.
I am, however, concerned that neither the owner nor broker know such basic information about the engines.....that's pretty scary and telling.

My 8v71ti are 435 hp.

Again - an engine survey by a reputable Detroit mechanic will tell all regardless of who says what about them.

You may find the broker and owner are only being honest.

We have a 1980 43 with Johnson and Towers 6-71TIs, 2800 hours and they run perfectly.

Engine survey is the way to go.

Hire a DD Guy that has references.

Expect to pay a few hundred dollars, and it is worth every penny

Get the hull ID number and contact Steve at SAMs. Hatteras will no longer give info out unless you are the owner. If you can get the serial number off the engines that would be the best. If the boat looks good and is something you think you're interested in, make your offer and then get a good surveyor. If your not sure what you're getting into, hire someone to look at it for you before you go through all the expenses of pre-purchase surveys. Sounds like you could use a good buyer's broker but it's probably too late on this deal if the broker has already shown you the boat. Let the broker get you the info you need. Remember even though he's the seller's broker, he also needs to represent you if he's acting as a dual agent.

Hours are not that good of a yard stick unless they are tach hours that register by RPM and not clock time. Billy Black charter Capt on the "Dutchess" out of Walkers Cay put 40,000 hours on a set of 8/71 N's. But the boat ran every day 7 days a week. MY's and DC's suffer from long periods of inactivity which is way worse on the engines than hours of operation. Engine survey is the only way to know whats up with the engines.

 

[Boatnut]

I agree with Jack. If the broker wants to move the boat it is his job to get the facts for you. Like everyone else says a survey is a must. By all means do not let either the seller or the broker choose the surveyor for you. Ask around even here on the forum, the owners here know who the good surveyors are.

Hopefully Sams will also protect their clients confidentiality and not give information to a non-owner too!

I wouldn't expect either to release any confidential info. I was referring to basic boat info. With the hull ID# they can tell you what she was delivered with. But that's not necessarily what's in there.

 

[rwappleton]

Many thanks to all posters! Good surveyor and Detroit guy located, Call in to the broker to make an offer...............More on this later.

[captddis]

That is good stuff. They make hats from that.
