    Merc 8.1L EFI Issue

    Hello, Haven't been on in awhile due to some personal issues. Went out a couple weeks ago and on the return the stbd engine would not start. After returning to the dock I noticed it would start for a couple seconds then sputter and die, but it was in gear, would not start after that. This is...

    Grinding Sound from V Drive

    One V drive is making a nasty grinding sound in both forward and reverse idle (and higher rpm) on our 2008 38DA. This is something I will probably not want to tackle myself. Can the V drive transmission be pulled without having the boat hauled? Thanks, Mike

    Door Hinge bolt

    Does anyone know what type of bolt SeaRay uses for the hinge on the stern door? This is on a 2008 38DA, the door is fiberglass with a SeaRay S in the center. The hinge bolt on the bottom hinge appears to have a Allen head set screw in the middle along the bolt center axis at the bolt head. I...

    Cool Fuel Raw Water Plug

    We have the Merc 8.1L and the cool fuel module raw water plug snapped off. This is the blue plastic plug used for draining water when winterizing. I checked the other engine and the plug was stuck and snapped off too. It seems the plug with o-ring was placed on the cool rule module before the...

    Hello, Anyone have an exploded diagram of the Kohler 7.3ECD that specifically shows the cooling system and thermostat location they could post? I have a slow overheating problem and have changed the impeller, back flushed the heat exchanger, purged any trapped air pockets in the coolant...

    Kohler Running Temp Hot

    We have a Kohler 7.3ECD Low Co generator that is running hot around 210 degrees. Long story short is, I have replaced the impeller (the replaced one was fine, no vanes missing), flushed the heat exchanger backwards with hose (small amount of sand was in catch bucket), bleed the coolant for air...

    Kohler Overheating

    We ran aground awhile back and I have been slowly working my way through things and finally got around to the Kohler 7.3EC low CO generator. When we ran around the generator stopped due to sand intake I believe. Later I cleaned the strainer and restarted the generator, it ran fine and water flow...

    8.1L Raw Water Pump

    How easy is the raw water pump on a (2008) 8.1L to turn by hand? I have pulled the pump and the impeller looks fine, flexable and no sign of any degradation. I can rotate the pump but it does provide some resistance. The impeller was replace less than 50 hrs ago. We ran aground and the raw...

    Hurricane Pass

    Well after getting the manifolds done and fixing the design problem with the AC I was ready to watch the sunset last night. We left the dock about 6:30p heading out Hurricane Pass to the Gulf. I had created waypoints thru the pass a couple years ago because the charts are not even close and the...

    CruisAir Compressor

    Our boat has a Crusair SXUF-18/1HV-RMT-53ISO compressor/filter fan assembly. The AC went out and this is the first chance I have had to look into it (compressor was not running). At first I thought it was the run capacitor was bad because the wire (R/W) from the circuit board to the compressor...

    AC Problem

    Just got the manifolds changed and now the AC died. Seems the compressor isn't running, the fan and water pump run but not the compressor. The AC is a Cruise Air Model SXUF18/1HV-RMT-35ISO, Product # 205-311787. Anyone know if a fuse is on the control board module, or maybe a breaker hidden...

    Another Exhaust Manifold Question

    Have been following all the discussions on manifold and risers/elbows for awhile and was planning on replacing ours late last year. Family issues prevented this as they have prevented our boat use lately. I started to worry when the expert folks were saying that its not only the hours of use but...

    Generator Zinc Replacement

    We have a Kohler 5KW Low CO gas generator. How often do you change the zinc (boat in salt water here in Clearwater)…any tips on replacing (it's located behind a short 3~4 " hose that looks like it must be removed to get to the zinc)? Thanks and wishing a Happy New Year, Mike

    38DA Manfolds & Risers

    We have a 2008 38DA with Merc 8.1L engines with 240hrs. I think it's time to look at the manfolds and risers....and replace if needed. We are in Clearwater, Florida in saltwater. Is this a do-it-yourselfer for someone 65? I have done most of the maintaince on the boat from cleaning, componding...

    Carpet backing

    Our 2008 SeaRay 38DA cockpit carpet backing is deterorating. Basically the black backing is crumbing and making a mess, and some has stuck to the cockpit fiberglass floor. The front of the carpet is Ok and don't really want to buy new carpet. Any suggestions on if one can "recoat" the back of...

    Northstar NS100 Handset

    My Northstar NS100 Handset cord has begun to fall apart. I understand this is a common problem and the NS100 is no longer available, including parts. Anyone know a source for the cord or replacement handsets. I really don't want to replace the entire VHF radio, nor try and use a non-stardard...

    The horn on our 2008 38DA died. Today I removed it (2 sections) and it was badly rusted. The brand is Nikko and YML model. Anyone know where you can get one outside the usual MarineMax SeaRay dealer. Thanks
