    My 340 Sundancer is on land and I'm looking to warm up my 8.1 motors to give them an oil change (first time as a DIY). In order to get water pumping through the motors to reach operating temperature, do I just place a hose in the bucket where the strainer is with a closed sea cock? Or am I...

    Westerbeke 4.5- proper way to test switches / sensors

    My 4.5 westerbeke shut down on me while I was actually watching the exhaust pumping. Was running fine, then a little white smoke and then dies. It ended up being the belt on the water pump which actually broke. Anyway, I changed the belt, and now the gen won't run unless I depress the preheat...

    New Impellers on 8.1s - Exhaust Discharge Now Not Flowing at the Same Rate

    Had both impellers changed on my 2002 340 with twin 8.1s, after concerns on running my port side dry for 5 minutes. Upon replacement there was no discharge out of side ports until the mechanic introduced a hose into the strainer to prime the pump. --Coincidentally this happens also when I splash...

    Inboard impeller question - fried or not???

    My boat was launched this weekend. Once in the water, I started it up and went to pay the hauler. When I was going back to the boat I noticed no water coming out of my port exhaust and started noticing some smoke. Temp hit around 160 and I shut it down right away. I checked the strainer and it...

    Sorry for the long winded post, but this is my first time winterizing Fresh Water Cooled 8.1S.

    Can someone please help me on the proper procedure to adjust the steering wheel on my 2002 340? Would like to tighten it (moves back and forth 1/8 of an inch if I jiggle it). Also, if possible I would like to center the emblem on the wheel to match when my rudders are straight. Thank you

    Steering / Rudder Angle Question

    On my 340, I do not have a rudder indicator, so I always used the rule of thumb to count the rotations of the steering wheel then divide by half and I would have my rudders straight. So for the last 2 months (since I've owned this boat), I always had 5 rotations in my steering wheel, so at 2.5...

    Underwater Exhaust Question

    I just purchased a 2002 340 DA and blocked it up in my yard to bottom paint and detail. I noticed theres a gasket between the underwater exhaust (bullet) and the hull. It almost looks like there is a 1/32" space between the gasket and the hull. Should the area around the gasket be siliconed or...

    8.1 not pumping at launch unless primed

    went to look at a 2002 340 sundancer with 8.1s yesterday which they were launching when we got there. They installed new impellers last year. However when they launched it, water wasnt coming out of the exhaust. They had to put a hose in the sea strainer, then they were pumping fine and strong...

    Merc 8.1 How do I know if manifolds are Aluminum or not?

    Im looking at a 2001 340 with 8.1s in it (picture below). After reading a few posts, it seems like the first few years had aluminum exhaust manifolds. Is there anyway to tell if the manifolds were updated? Is there anything else I should be looking for in these motors? Thank you very much.

    7.4 or 8.1 in a 340

    I'm looking at two 340 sundancers this weekend. A 1999 with 7.4 horizons, and a 2001 with 8.1s. All the 340s I have seen so far have had 7.4s. Is there one motor that is hands down better? I know a bit about the 7.4 just from having two boats surveyed already. However I'm not too familiar with...
