    Air condition not working

    So put the boat in yesterday and the AC is not working, specifically the pump. The fans and compressor come on but the pump does not. So checked the circuit board terminals and have 120V at the input terminals but 0 volts at the terminals going to the pump. It's a Cruisair single unit system...

    winterizing merc?

    2006 Mercruiser 5.7 TKS (turnkey start) in a 2006 Crownline 250CR. I have the manuals and in the past I have always used my Campco winterization kit where you fill the jug with pink then connect your garden hose to the T on the jug and warm the engine off the garden hose. Once warm you flip the...

    swim platform rebuild

    So very early in the process here (just thinking out loud now) but my swim platform needs a rebuild. It is a bolt on with a soft spot just behind the transom door. There are 2 vents and the soft spot is right near the one so my guess is it wasn't sealed very well. Had the boat surveyed last year...

    pontoon won't start

    So my mother and step-father have a pontoon they bought last year. They have been having trouble a few times this year with a dead battery. I knew they had 2 batteries but did not know they had a Perko switch installed. I thought he just had the 2nd battery and manually switched it. Anyway, we...

Took the carb off last weekend to rebuild it and put it back on today but when i went to test the throttle it was very stiff. throttle lever on the carb is smooth with the linkage unhooked...

    oil pressure question (pretty high)

    So had the boat out yesterday and today and noticed pretty high oil pressure. We just bought the boat last August but the boat was docked across from us in 2015. Only ran it a few times last season and never noticed it but noticed yesterday and today that it was running around 70-80 PSI while...

    port window 'dogs'

    So I have a missing dog (latch) on one window and a broken one on another. Trying to find them on the internet but no luck. Anyone know where I can find these and are they pretty much interchangeable across brands? Mine is a 2006 Crownline. Not sure what brand the windows are. Will check today...

    fuel gauge not working now

    Not sure if this should go here or electrical or Mercruiser...lol. So had to drain some fuel from my tank and pulled the sending unit to get a hose in there. There are 2 wires attached to the sending unit (red and yellow). After putting the sending unit back in now my gauge isn't working. It is...

    trailer brakes locking during backup

    So bought a new 2018 2500 Ram a couple weeks ago and towed the boat for the first time today. Everything was fine until I tried to back up my driveway. Brakes were locking up on me. I have the 5 pin to 7 pin adapter and it worked fine on my old truck. etrailer.com says the center pin should be...

    New Rule shower sump (no output)

    So ordered a new Rule 98A shower sump to replace my old one. Got it all hooked up and added water. Pump kicks on when float triggers but nothing comes out. Checked the output hose and it's clear. Can blow through it with ease. There is a pinhole at the top of the output tube coming out of the...

    swim platform soft spot

    so I have a soft spot on my swim platform just behind my transom door. The platform is a bolt on and the soft spot seems to be about 15" around. There are a couple tiny hairline cracks that ooze brown out that I assume is rotten wood? There is about a 4"x4" pad underneath that supports the...

    remote oil filter install?

    So I assume it's possible to install a remote oil filter on a Merc? Have a 2006 Crownline with a 5.7 (non EFI). It has the outdrive oil monitor on the front above the power steering pump. Tried changing the oil today and can't even get my fingertips on the filter. My step-son is alot skinnier so...

    Bunk vs transom relationship

    Probably asked on here 1000 times but on another forum I am on a member said Sea Ray recommends having the bunks stop about 4" short of the transom? Doesn't make sense. What brought up this topic is he just bought a brand new Venture trailer identical to mine and I noticed in his pics his winch...

    28" turnbuckle (or alternative idea)

    So my last boat had a turnbuckle that went from the bow eye to the winch post on the trailer. The new boat (2016 Venture trailer) has an eye at the base of the winch post that I was going to buy a turnbuckle and do the same but it needs to be about 28" total length. I haven't found one that...

    2006 Merc 5.7 engine oil?

    So my boat is at a local shop for bellows replacement and my manuals are in the boat. Went to buy stuff for winterization but wasn't sure what oil to use. In my 1986 Sea Ray I used Shell Rotella 15w-40 T4. The new boat is a 2006 Crownline with a 5.7 Merc B3. It is not fuel injected
