Default Advise on 1987 35ft Viking

I’m buying an 1987 35 ft convertible Viking! Does anyone have any advise on the ride? It has twin yanmar 315 engines with 475 hours on them. When the gen runs is it loud in the cabin? Any advise would be great. Thanks

Great boats, doubt genny would be heard while mains are running, probable has water lift muffler so most likely quiet. You say you are buying it, (not meant to offend) but just the 2 questions above suggest you have very little experience with boats like this. If that's true, hire the best marine surveyor you can find and a yanmar mechanic to do your inspections. You'll have to spend a grand or two but they can potentially save you a fortune in headaches and cash. I suggest you immediately join boatdiesel.com and start reading up on those engines. Welcome to the twin screw club it's a whole different thing than ob powered boats, gl

Why not take the boat for a sea trial and form your own opinion before you buy it? It's a generator, they make some noise. It's a 20,000 lb Viking and will ride like one.

Thanks everyone for their replies. I’m concerned about the gen running when the engines are off. How loud is it? I’ve
ridden in a an older Viking and not concerned so much about the ride. The way I understand it, it’s like a tank. And I’m going to do a sea trial and marine survey before I buy.

No way of knowing until you sea trial it but it won't be so loud as to completely bug you. We have a 20kw and an 8kw and you'd be surprised how often you actually use them, rarely. Unless you are going overnighting and needing AC, a good inverter will supply most of your electrical needs.

Are those 6LP yanmar engines? Been repowered? There were some valve issues on some early 6LP's if that is what they are. Good engines otherwise, but need the valves replaced if in the affected batch.

315s are going to be pretty slow. I had the 370Bs in a 35 Bertram and it was good but no speed demon.

Is the genny in a box or just "willy-nilly" installed without options to quiet the genny?

This... we run a big Westerbeke in a ‘78 Viking 35 and can barely hear it running with the mains shut down.

That boat is a LOT heavier than 20k. I believe our 33’ was 28,000. Your point is valid though.

What make/model/size gennie is it? Some are by nature noisy. Some are naturally pretty quiet, but a bad install can get noise into the boat.

I spent a couple years deck handing and essentially living on a 86or87 35 viking back 20 years ago. I dont remember the generator being a sound issue at all.

Hello, I need some advise on the ride. I heard the the ride is horrible in a head sea in an 1987 35 Viking. Is this true? Thanks Jonathan.

What is the cruise speed at 2750rpm? And what is the fuel flow. It has the yanmar 315s. Thanks Jonathan.

Yanmar 315's seem to me like they are small for that size boat. They put a pair of Yanmar 315/s in Carolina Classic 28's that weigh in at 16k lbs. The Viking 35 has to weigh twice that much.

I was told the 35 Viking weights 20,000lbs. Is that correct?
