Missing sensors and a ?

[Bill with a seaswirl]

Back again! So, the engine I'm putting in has nothing in it for sensors and such, does any one have a link th where all the wires go and the sensors that should be in there? I need to go buy all the sensors soon. 1998 seaswirl 250 aft cabin, 5.7 gs I have looked but just don't seem to be able to find it.

Second thing. What is the big electric box on the manifold that looks like it has a breaker switches in it. Has a round plug in the front of it. Clymer manuals suck

You need to buy an OEM manual for your engine. What is your model number?

That box normally contains the breakers the the start assist solenoid but may vary depending on model. The plug is for the engine harness where the boats harness plugs into.

boat info now has the volvo manuals on line http://boatinfo.no/lib/library.html#
here is a link to get the factory OEM manual http://www.volvopenta.com/volvopent...lication_search/Pages/publication_search.aspx

next question. why do you need a manual to know where the sensors go on a carbureted 5.7? water temp sensor (brown wire) goes in the intake manifold on starboard side. oil pressure sensor (blue wire) goes in the oil pressure port behind the intake manifold just port of the distributor

Main question in my head was if there was a knock sensor. I'll check out those links and I have to get a proper manual. The Clymer doesnt tell you much to say the least!

Did you have an engine in your boat and you replaced it with another one?

The old motor cracked the block on the previous motor. I got an empty engine bay and a complete longblock with nothing on it other than intake, oil pan and water pump, timing cover. No hoses for the manifolds either.

 

[bruceb58]

So...I take it someone else took the old motor out and sold you the boat?

Correct, so i have no mental picture of what it is supposed to look like in there. No idea what I'm missing either until i stumble across it. Going to be a bit challenging but I'll get it figured out. Hopefully sooner than later!

The problem with the manuals on boatinfo is that the circuit drawings are not in color like a real manual and almost impossible to read. I would invest in a set of real OEM paper manuals for your model.

Thanks for the pointers so far folks! How about another q? The exh connection from the riser to the y pipe is missing...$$$$ What is the proper terminology for that piece? It's MIA.

Upper exhaust hose. Try part #3852596? 4 clamps on each hose.

 

[Scott Danforth]

3852596 is a lower steering pivot bracket

 

[Scott Danforth]

if its a 4" exhaust hose, they are common and cheap... if its the 3-3/4" exhaust hose, they are expensive. let me know if its the 3-3/4" diameter

3852696... sorry. Fat fingers. Just a guess on that part number though.

So I measured the exterior diameter of the Sierra risers and the best I can tell is that they are 3-3/4 outside diameter. The y pipe diameter appears to be 3-1/2 inches. Would I be going in the right direction to have an exhaust shop fab some up for me?

 

[Scott Danforth]

No need to fab anything. A piece of rubber exhaust hose goes between the two and is secured by two clamps.

3 and 3/4 hose on volvos is a bit more expensive than normal 4" hose

So I talked to the guys at west marine. They have 3" wire reinforced exhaust hose...

I use 5 layer nomex and silicone 500 degree turbo hose. Its 1/2 the cost of the 250 degree exhaust hose. Hit up any diesel service center, or check eBay.

I picked up mine for $60 for a 4' length. Most places had the Volvo exhaust hoses at $50 Each when I was looking. Each hose should be about 8" long.

Good tip Scott! The Volvo counter guy even mentioned turbo hose. Man oh man is this getting to be quite the project... Was going to mount the alternator to check hose clearance issues, it's frozen solid and missing the mount that you adjust the tension on. Motor mount adjusting bolts are rusted to where there are no threads and so on.

This but a flesh wound!
