2008 280EC Rotten Transom

Squatch68Squatch68 Ottawa Valley, Ontario, CanadaMember Posts: 43 ✭✭
Well folks, I was just finishing up the job replacing the swivel shaft seal using the JR Marine kit (which is fantastic btw) when I discovered something I hoped to never see.  Was cleaning up the area where the steering arm goes through the transom assembly on the inside of the boat. Moved the wiring harness that runs across the top of the transom where it transitions to the bottom of the swim platform. Discovered the thin fibreglass layer was cracked along the entire top edge and the wood soaked and rotten. Chipped off some fibreglass lower down around the transom plate and it's soaked all the way down.

Through more investigation discovered that water has been coming in through retractable cleats on the corners of the swim platform, then running across the swim platform and then down into the bilge.  At some point there must have been a defect or something in the fibreglass which allowed some water in and it's just continued to get worse with time.

Didn't notice it when I bought the boat this year since it was under the wiring harness. Man do I feel like an idiot. 

Had my local shop take a look at it yesterday. They are going to attempt to repair early in the spring. Pull the engine, pull transom assembly, cut out the fibreglass on the inside and just hope its only the inner most piece of wood that's been affected.

    My Riker 235 had similar rot.  The starboard side of the motor mount/stinger was solid but the water was able to wick to the port side and took out the wood under the batteries and water heater. It extended to the wood that goes between the fuel tank and engine compartment.  Also took out wood half way up the port side of the fuel tank. 

    I had to remove the aft bed floor to access all this.   I put in a fuel tank while it was out and easily accessible. 

    In other words, I'd try to get the shop to look at it over the winter while business is slow and not come spring rush.  Will give you time to prepare for any unexpected costs.  I did all the work myself and I'd estimate about 2500 to 3000 in materials including fuel tank. 

    While I doubt yours is bad I have seen the rot travel from leaky swim ladder all the way to the v berth.

    That's crazy @PickleRick, amazing how water can seep and travel and create quite a mess! Smart to replace the fuel tank while you are in there.  I am making a list of things I want done while the engine is pulled. 

    The hope was they would be able to do it over the winter but unfortunately the boat is just slightly too large to fit into their heated shop. They don't have time to do it before the snow flies and need temperatures to stay above freezing overnight. Early spring is as good as its going to get I'm afraid.

    It's a job I wouldn't mind tackling myself but there is no good way for me to get the 496 out myself.

    Surprised a survey did not pick up on that, most surveyors will definitely check the transom area especially with a drive attached for moisture. I had high readings and posted about it over last winter. Make sure your shop is experienced with this type of repair it can get very expensive.

    @Squatch68 thanks for the reminder:  I had written up a list of jobs to consider during engine removal, but forgot to post it.

    Not sure how the 280 is built but the 330/350 of the same era has open unsealed wood at the base of the transom where the garbord plug is and at the stringers where the holes are cut to allow water to migrate to the center bilge area. 

    I believe these are some of the concessions of having a boat that was built to a very affordable price-point.

    I had to get the motor out of my 270....I un did everything, took it down to the marina and they put some chains on it and lifted it right out. I had a U Haul trailer, built a engine stand of sorts with wheels, took it home and rolled it into the garage. Now a far as dealing with a boat with no motor and living where it snows, your on your own from there as I live in FL! They used the fork lift they use for dry storage lifting....in and out was 200 bucks I think it was...

    YYRC, are you sure that the garboard plug area and the stringers in the engine room are not sealed?  It seems to me that if that was the case, we would have a very large number of Rinkers with rotten stringers and transoms.  I could see maybe a few boats built where sealing these areas was missed but it would be shocking if this was Rinker's policy.

    Neither my 330 nor my 350 are sealed at the cut-through for the stringers. The transom cutout at the garbord plug does not appear to be sealed, either. 

    Reach your hand down to the stringer cut-through and you can feel the wood.

    I know the stringer isn't sealed but I can't imagine the drain area not being sealed. How did you verify this did you remove the plug and the base?

    My 2014 EC 360 was sealed in both areas. There were a couple of areas in the bilge that water should not have pooled under any circumstances and I marine epoxied them with two coats just to be safe. When I pulled the engine of a the Rinker that we built from a 350 mag to a 383 I sanded and marine epoxied (two coats) the entire bilge. When the engine is out I'd also replace the oil pan.

    I took this pic today. You can see that the transom wood is “painted” with resin and not sealed to the hull next to the stringer. You can also see that the upper hole in the stringer is sealed (tho cracked over time) but the lower stringer holes were not sealed. 

    Just seems a bit sloppy to me.

    I forgot you have a twin engine so you can see your drain from the inside.

    What a PITA boats are

    Ever heard of pursuit boats?  Not exactly a budget brand line of boats.   They are wood cored with balsa, in the hull.  Below the water line.   

    Keep the mind the infusion process in which they apply the resin 100× better than the dreaded  run away as fast as you can boats from the 60s and 70s.

    Wood is strong and saves weight.   

    Even pursuit has examples of some Friday boats.   Happens in all brands, rinker is no exception.   Im willing to bet rinker had less boo boo boats  percentage wise than sea ray.

    I would really like to see the actual proof of this “rotten” wood.

    I would like to see pictures as well.

    A dock neighbour showed me his 330 two years ago. The inner transom skin was cracked exactly as @Squatch68 described above. The 330 owner said when he removed the screw that holds the oil drain hose in place, water drips out. 

    For us northern folk, when the boat goes out for winter, I believe the water in the transom freezes and expands and further cracks the inside skin of the transom. Cycle repeats each season, getting progressively worse. 

    All said, I’m not sure where the 330 owner’s leak was from - obviously many possibilities - but his transom was saturated. I didn’t have these saturation issues with my former 330 or current 350 but both have some horizontal cracks on the inner transom.

    Gel cracks do not constitute rotten wood.  Heck, even water saturation does not prove rotten wood.   Just curious to see a sample of the rotten wood

    Rotten or not, it is a design flaw and/or quality issue.

    How did you know????
  • PickleRickPickleRick Member Posts: 3,236 ✭✭✭✭
    My parents have a sub 10 yr old 5th wheel that is proof of RV water leaks.  Sadly the full coverage insurance didn't cover damage.  

    It now sits under a 12k car port.  

    If you have just a wet transom you may be able to remove all transom fittings and store in a heated storage.  Wet doesn't mean rot but if caught soon enough may be able to be dried out.

    Well I'm still here. :P I'll never own another boat with anything mercury on it and I prob wont ever own a rinker again! 
  • Aqua_AuraAqua_Aura Lower Columbia River, WashingtonMember Posts: 2,107 ✭✭✭✭
    I agree with the Mercury part of your comment. 🙂

    Jeff, what’s your beef with Mercury and Rinker?   Rinker just started putting Mercury outboards on Rinker boats.  Outboards are not my favorite to work on but they really don’t have many issues.  Most Rinker’s came with Mercruisers some with Volvo penta

    Screw merc...its Konrad or nothing now.  

    Big duramax 500hp 6.6 twin turbo in a 21 ft runabout 

    My question is, who's gonna bank roll this new float for us?


  • AlswaggAlswagg Member Posts: 2,964 ✭✭✭✭✭
    Pickle, I’ve got 4 diesel we service one Cummins, 3 Volvo’s.  All are nasty to work on yes they just keep running.  The Volvo’s hour meter stopped several years ago at 7,000 hrs. All three in the same hull.   The Cummins has now over 5,000 hours.  The only real issues we had is injector pumps and lines on the Cummins.  The Volvo’s have coolant leaks from the thermostat housings which are aluminum.  Otherwise they just keep working. 
  • YYZRCYYZRC Georgian BayMember Posts: 2,730 ✭✭✭✭
    I'm with Jeff.  Would avoid Merc at all costs. If I ever have another I/O I hope I can find the boat that I want with Volvo power.
