    VP 3.0 GS PWTR s/n 4110177147 plug wire routing, model year 1999

    I've been having a few issues w/ my engine, and when I replaced my cap/rotor last year, I researched correct plug wire orientation. Now I need to re-confirm. I think the diagram I found online may not have been engine or s/n specific, and I see Merc uses the same block/distributor, etc....and...

    VP 3.0 GSPWTR starts, wont' run; fuel filter, bad gas; post winterizing issue?

    Help identify SX drive gimbal bearing part/seal that came out during inspection

    Hi All, I have a '99 SX M drive, and I pulled the drive to replace the bellows and inspect the gimbal bearing. There was a lot of grease around the bearing, so I placed a finger in to clean some of it out. From the back side of the bearing, a "part" came out that looks kind've like a...

    1999 SX drive u joints have zirk fittings; does that mean they've been replaced?

    So I bought the boat this summer, and ran it until winterization time. I got the drive off, with the intention to replace the bellows, gimbal bearing, and inspect the u joints. U-joint area is packed full of green grease; to me that means they topped it off each season, but didn't replace the...

    Need to locate all water drains on VP 3.0 GSPWTR for winterizing....

    Yup....I need the service manual. I thought I had it, but it's the generic manual, and does not show everything that needs to be removed from the block or manifold to drain all the water. I've already pulled most of the hoses, and impeller housing (it's getting replaced anyway), and have...

    Theoretical Volvo 3.0 (any model) question: timing versus manifold vacuum readings

    OK so Volvo's engine manual (downloaded--thanks DonS!) utilizes manifold vacuum readings at idle as the primary metric (measuring stick) to analyze engine performance and as a diagnostic tool. And from what I see, it doesn't even have a really great explanation for setting timing w/ a...

    4 blade for Volvo Penta 3.0 liter GS SX Drive; go from 19 3 blade to 18 or 17 4 blade

    Boat/motor are 1999 Regal LSR 1700 (17ft) with 135hp VP GS/SX inboard. Rated RPM is 4200 to 4600. Current prop is factory 14.5 by 19 pitch factory 3 blade aluminum, with very minor imperfections that I filed clean. I've run the boat up to 4300 RPM WOT with driver and one teen. 1/2 tank of...

    Trouble with loading; hull doesn't always stay in contact with front roller?

    Tried to search for this problem, but didn't find any exact phrases, so here goes: Here's my setup: 17ft Regal LSR 1700 with Fastrac (multiple "steps") hull. Eagle trailer with bunks custom set by manufacturer specifically for this boat and hull. I launch deep so the boat floats off...no...

    1999 GS 3.0 GSPWTR throttle cable doesn't seem to have enough adjustment

    Re: 1999 GS 3.0 GSPWTR throttle cable doesn't seem to have enough adjustment Don, Here it is; rather poor light. The actual part is 36mm long (1.41") Thanks Again!

    1999 GS 3.0 GSPWTR throttle cable doesn't seem to have enough adjustment

    When I took it off for carb rebuild, it sprang forward 3/8" from idle position. After rebuild, carb is running well and mostly tuned, without cable. Tried to turn cable end in; it stops about 5/16" too far from attachment. Looked (and got head stuck!!) under gunwale at the controls side...

    1999 GS 3.0 GSPWTR how does the main pulley (harmonic dampener) get bent and wobble?

    I went over most everything with the previous owner, including him showing me all the new belts, and all the pulleys that I could see ran true. Doing my carb rebuild, I was shining a flashlight down toward the forward engine mount while running, and can see the main pulley is wobbling. The...

    1999 GS 3.0 GSPWTR oil sheen on water in driveway after carb rebuild?

    OK got the carb all rebuilt. Put it back on, turned the engine over w/ the key for 5 seconds to get fuel going...stopped, manually pumped carb throttle until a few squirts came out, then hit the starter again. Fired up, only 150rpm low. Tweaked master idle to get up to 700 rpm, and left it...

    End caps on SX-M hydraulic trim cylinders; do they keep out corrosion?

    I have one missing; two come off with no effort at all. It looks like someone half heartedly filled a part of them with black silicone when installing. The other one had a half moon of cracking rubber peeling off. Running in fresh water only; how much will these poorly sealed caps impede me...

    Master guide to tuning 1999 3.0 GS Holley 2 Barrel Carb (looking for editing remarks)

    Did quite a lot of reading on this from many sources, including Holley service manuals. All have some minor detail left out. My first thought is this, (assuming just tuning, or just after rebuilding and reinstalling). Warm up engine to full operating temp. Adjust choke first; all other...

    can trim senders be disassembled, or are they embedded in potting compound?

    And why try taking the measurements with cumbersome clips and activities at the transom...my disconnect is in the engine compartment, tied to part of a main wiring harness...so why not disconnec there? And for that matter, why not just disconnect the two leads at the meter to set the 11 ohms...

    1999 3.0 GSMWTR too much oil in crankcase (not water, apparently overfilled)

    So yes, of course it's a new-to-me boat and I'm a boating newbie....previous owner and I reviewed oil level during purchase, etc..etc... I've had it out four times...each time I checked the oil I thought it was high on the stick due to the angle of the boat sitting on the trailer, as I have to...

    1999 3.0 GSMWTR carb idle adjustment versus full carb tuning procedure

    OK so she was idling rough and low (on-land numbers with hose/ears)...about 550rpm in neutral, and about 500rpm in forward and no extra throttle. Closer to 400rpm intermittently last time I had it in the water, fully warmed up, in neutral. Pretty shaky too. I've read about changing the two...

    1999 3.0 GSPWMTR spark plug gap

    Hi All, Bought a '99 Regal LSR 1700 with the above-mentioned motor. Changing plugs out. The old ones came out at .040", which I think per the Volvo site, they should be .045". However, someone posted an "addendum" to a '99 Volvo manual that shows a gap of .060", but it didn't have detailed...

    Can Faria trim gauges be adjusted? Mine is off by quite a bit.

    My trim gauge works, but full down shows maybe 3/4 down, and full up goes off the scale beyond the yellow zone. I used to work with gauges; is it as simple as removing the face and replacing the needle?? Thanks!

    How accurate are pressure speed tubes? What if they're drained?

    The kids lifter the speed sensor arm; it drained water. It will show almost no speed until about 15mph, and then jumps to 25 with very minor throttle. Do they need to be lubed or something at the plunger? Should they be drained and refilled? Are they filled automatically when lowered? I...
