Viking Owners a Special Breed?

It is definitely not in the ER. Not quite sure why the manual would show that. Are you certain that the manual is for your boat?

Yes, the manual is for my boat; however, I am finding this is one of many things that were apparently options. My manual refers to 8V92's but I have J/T 671TA's. Also, the manual describes electric heads, while I have vacu-flush units. The photos show the valving on the port-side ER but on mine one of the vacuum tanks is located there. It also says the holding tank is under the generator whereas mine is forward under the fwd head. My aux fuel tank is under the generator.

Paperworks says it was built in NJ and it has the "Jersey" space heaters as standard equipment. I think the problem (according to Viking Service) is that my hull is 1989 but the features are actually 1990.

But now I have everything located. Removed/rebuilt both starters, changed all the fuel filters from the Dahl models to newer/easier Parker/Racor models, upgraded lighting, switched and electronics and replaced the top and all the eisenglass. She's come a long way. Very happy with her.

The locations you describe are the same as mine. I have never seen this boat with anything other than 671's. I don't think that 8V92's would even fit in this boat.

That's EXACTLY what I thought when I was paging through all the books/manuals left aboard. Outboard of my engines is all intercoolers and giant muffler systems. 8V92 would be a squeeze, to say the least.

Manuals are type-written too which (I suppose) is common for the era and the constant upgrades and changes made, not to even mention the different building yards. There have been many times where I have done batter just following lines/wires/hoses and the like to figure out what is where. I am SURE you've done the same thing. Thanks for your help.

Have you made your trip yet?

A friend of mine owns a 41' Viking SF and it has 8v92's in it.

The motoryachts were built by Gulfstar, which now is Known as a company called "Lazzarra". Which is the Lazzarra we know today. You can call them with questions and they can be helpful also.

8V92s in a 41 Viking?
I know 671s (Ns through TIBs) were common in the 41 Viking.

I am surprised that 892s fit in the ER of a 41 Viking.

That boat must fly.

Not really at 1850rpms it ran 21-22knots. At cruise 1950-2000 rpms it ran 25 knots or so.....it was a 1988. I ran a 2001 50' Viking with 1050 MAN's and that boat flew, it cruised at 38 knots.....

I ran a 1978 41' Viking SF with 6-71N's and it was SO LOUD at idle speeds and hull speed that you literally needed ear muffs while on the FB. It was beyond horrible....I remember it cruised around 17 knots....

Did he repower it himself?
Can't find any Viking 41, 1990 or older, that has anything near an 8V-92 from the factory. A few re-powerd with Cummins 8.3's, at 430 - 480hp.

Was this a factory "special"?

No, it was ordered from the factory that way. The owner lived in Brielle, NJ. So he probably visited the factory and such. It was a one stateroom boat as well. The owner still owns the boat. He had a full time Captain up until about 7/8 years ago. Has a Hardtop, no tower, no tender.

1991 Viking 72' CPMY

New to Viking ownership, looking to converse with other like owners about maintenance, upgrades, etc.

We bought a 1985 35' Viking Express with a pair of 320 Cats and a tower. Initially hunted for a 32' Topaz, but couldn't find a decent boat. The 35' Viking popped up and she fit our requirements well - now we're glad we went with the Viking. In the past 2 years we've put about 475 hours on her and have thoroughly enjoyed her. She is reasonably economical, built well, and handles offshore seas well. I agree with all the preceding comments, they build a nice boat!

Or truely a Viking as it was built by Gulfstar and rebranded.

I am a very happy and proud owner of a Viking, been through some rough stuff and a Viking will get you home. One tropical storm beat us to death. The Viking just thought it was a Tuesday and never missed a beat. My sweet beast is a 1976 43' DC. I do wish I could get hands on some manuals, especially electrical wiring, as over the years some rigging has occurred by previous owners. Only basic normal repairs for me so far, and 671N's that love to run.

Well I want to thank you for your wise and accurate input. We did make the trip in about 7 1/2 days. I did do redundant charts and plotter. the paper charts were so valuable as we headed into TS Andrea. did not get electronics up and operational until after storm. was an amazing trip, though no real time for leisure except short break at St Joe. Made two jumps one from Clearwater to Government Cut. then St Joe to Pensacola. I will say after storm my confidence in the boat was strengthened, and she lived up to the name and hype. Double tough boats! She has never let me down since, though the projects continue on. I will say I am not anxious for any more night jumps. My experience continues to grow as my pocketbook continues to shrink, but I am sea happy

I am considering the purchase of a sweet, 1987 freshwater Viking 44 motor yacht. I haven't seen anything posted in the forum about the Detroit 671TIs. Can anyone attest to their reliability and performance? Thanks!

671's are considered to be D.D.'s most reliable and longest lasting engine. So long as they're not the 480hp TIB's (3500hr-5000) they'll go a long long time at the lower HP levels.

No, I believe these are the 450 HP version and they have approximately 800 hours on them. Thanks very much!

Would also love to know the bridge clearance of the boat and if the bridge clearance number includes the nav light mast height.

I have Johnson & Towers (NJ) 671TIBs in my Viking 44 Aft-Cabin M/Y rated at 480HP and I honestly cannot tell the difference between 450 and 480; although there are certainly some owners who can. For my cruising and living needs, it's just power when you need it; and I usually don't need it.
The only difference between the two is at aft-oil-cooler system. I also have fuel coolers but I think the 450HO models also have them. Everything including the transmission is cooled by the main raw water system. It's just a little more complicated than the TIA. And I believe my oil pans are bigger, each engine holds 10 gallons SAE 40.
Main issue is using them. They like to be run and not just idle speeds. I try to take mine out the inlet regularly just for exercise and to run 15-20 knots for a while. On sea trial, she achieved 23 knots but that's more for the "canyon guys" than for me. Since this is my home, I don't "look" for 4-foot seas but I don't fear them either.
I'll post some photos as soon as I can figure out the protocol.
