    I posted this question in the Factory category too. What size stuffing box packing should I use? The prop shaft is 1" in diameter. Also, is there a preference as to which type of packing is used? Kevin

    2007 R-21 EC shuddering at start up

    When starting our Yanmar 3YM30 it has a brief but noticeable shudder. The shuddering lasts only a split second and then the engine settles into a smooth idle. I've checked the engine mounts etc and everything seems snug. The rubber has not deteriorated, as far as I can see. No cracking. The...

    R-21EC Yanmar motor mounts

    Similar to a previous motor mount post for a Volvo on a R-21, I am looking at a set of Novibrasyon mounts for my Yanmar 3YM30. The entire set of 4 can be had, including shipping to Canada, for one OEM Yanmar mount. They look exactly the same, even have the crease in the top part. They're made by...

    2007 R-21 aft deck cushion colours

    Does anyone know the colour code or name of the cushions we have on our 2007 R-21? Please see attached photo. I'm hoping that someone has refreshed their cushions with new material. I asked the factory but they no longer have that information. Kevin

    '07 R-21 EC prop zinc size and size of bolt

    Can anyone tell me whether the prop zinc is a C or a B? I purchased a C and it is quite loose, not nearly a snug fit. As background, I lost the zinc and bolt last season. What I've gleaned from a post in 2017 on a 2013 model year R-21, the zinc should be a C and bolt 5/16", 1 1/4" long with 18...

    3YM30 ELC complete evacuation in addition too using drain plugs... Necessary?

    Are there any hacks to ensure all the old coolant is removed? I am especially concerned with the heater core in the cabin. Any particular location good to use a vacuum or pump to empty system once drain plugs have stopped draining? Thanks. I was sure this would be in prior post but could not locate.

    R-21 EC Battery Trickle Charger Recommendations?

    I'm in my first year of R-21 EC ownership (also first-time boat owner), and trying to solve a parasitic battery issue. When I left the boat on a mooring for 2 weeks, battery #2 (house battery) would always be predictably dead. Yes, I made sure the 2 main switches were OFF in the cabin. Battery...

    Operation of cabin heater in '07 R21-EC

    What is the process to operate the heater in a 2007 R21? I've looked over the manual and it only indicates that there is a heater but no mention of how to operate same. Is it best to start the engine first and let it reach operating temperature before throwing the so-called switch? Is there...

    21EC fresh water tank will not fill

    On my 2016 21EC, i am unable to fill the fresh water tank through the fill cap. The just sits there in the pipe and rejects any water injected. I know the tank is empty because i filled it at the beginning of our trip, used a lot of water via the electric pump to the sink, and now that pump...

    Engine hour meter ('09 R21 EC) not working

    The engine hour meter stopped working on our R21 EC. Can these be repaired or do I need to replace the entire unit (RPM gauge and meter)? I've checked the wiring and contact points seemed fine i.e. no corrosion. My understanding is that they are a Hobbs meter so either record time when the...

    Bimini Frame and Cover for R-21EC

    Hello: I have a 2013 R21-EC that was not equipped with the Bimini frame and cover. Where can I have one built and installed? King Marine said they only do local or on site installs. I live in East Tennessee. Thanks! Steve

    Factory bilge pump in 2007 R-21 EC

    Hello. What was the factory bilge pump on my R-21? I can't make out the brand of the pump but it is red/black. What looks like the float has a label 'SPXFL'. Are either of this original? Also, should I be able to operate the bilge manually when I toggle it on (using the consul) regardless if...

    Hello. Can you point me in the right direction? I know nothing about how our toilet operates in our 2007 R-21 EC. I've looked at the manual but it doesn't provide much information. Thanks in advance. Kevin

    2007 R-21 EC Cabin heater plumbing query

    I've got another newbie question. If we're not using the cabin heater should the ball valve under the access cap, just aft of the door, be shut off? We noticed water coming from a hull drain, roughly mid-ship, when we hooked up our fresh water cooling system to a garden hose to run the engine...

    R-21 EC bilge query

    The bilge on our 2007 runs continuously when the console toggle is switched on. Shouldn't it be automatic? That is, only run when it detects water above a certain level in the bilge?
