Re: M_Boats: cockpit drainage on 1981 M17
tom: '81 was the year jerry retooled the M17's deck mold. does your M17 have the rear cockpit locker and two cockpit drains? or no locker, outboard motor cutout in the transom and single drain at the aft centerline of the cockpit? all of the 70s and 80s boats i have seen drain under the waterline forward of the transom (about 6") on the hull. not out the transom. if you have an above-water drain out the transom a prior owner may have modified the boat (which is good). you need to inspect the fitting. jerry installed a glassed in alum tube. very scary and can fail at any moment ... but fresh water sailing means you are better off than those that have salt water sailed boats. the test is to attempt to put your finger through the tube, or crush by squeezing with your hand. if you can damage the tube replace (ha ha). the cockpit drains on my M17 were replaced (still below the waterline thru-hulls) by the prior owner. i now have hoses and mushroom thru-hulls. a small child is a good resource. i have recruited a friend's 10 year old son to crawl to the transom to inspect and assist me in renovation projects. some folks have put an inspection port on the aft end of the cockpit footwell wall (for the 'old' deck design). for the 'new' design you can put an access port high up on the port and starboard walls in the aft 'wet' locker. FYI - the galley models also have an alum. fitting for the sink drain. this one is easy to inspect. replace if necessary as i explain above. my M17's prior owner replaced the old drain assembly. :: Dave Scobie :: M17 #375 SWEET PEA - www.m17-375.webs.com :: Sage Marine - www.sagemarine.com --- On Fri, 3/16/12, Tom Frei <tom.frei@gmail.com> wrote:
Greetings:
I have a 1981 blue M17. I've slowly been refurbishing it over the past two years. One thing I'm thinking about lately is the cockpit drainage. All I know about it is that there is a hole on the cockpit deck and a hole outside on the transom. I assume there is a hose of some sort connecting the two. The boat has always been sailed in fresh water and I'm experiencing no problems with cockpit drainage and the bottom of the boat floor always appears dry to me.
Should I worry about the connections involved with the drainage system on a 30 yr boat like this, or should I assume "no harm, no foul" and look at other things to fix? Tied to this question is another one: How would one go about replacing the hoses involved with cockpit drainage? It seems pretty tight to even get access to that part of the boat.
As always, thanks for your help.

Thanks Dave! My boat has no locker, a outboard motor cutout, and a single drain at the aft centerline of the cockpit. Your helpful information will set me on the right track. Thanks. -Tom On Fri, Mar 16, 2012 at 9:22 AM, W David Scobie <wdscobie@yahoo.com> wrote:
