HI

I have had my 28 since new in 85 and lately it seems that the rubber seal on the motor/leg has risen up more than I remember it was in the past.  I have never changed it as I didn't think there was any problem with it.  The alarm doesn't sound but it may just not work.  Is there any way to tell if it is leaking other than trying to remove the sensor?  I really don't want to do that as I think it may lead to more problems if the seal is leaking as I have the boat in the water all year. Our nearest haul out is about 60 miles away.  If I wanted to buy a trailer any suggestions on where to go to find one.

Hello Gerry,

On Page 24 of the Owner’s Manual is a paragraph entitled "Checking Saildrive Membrane Sensing Element." Following this procedure should tell you if the circuit is at least functioning.

In addition, I would strongly suggest you pull the boat at least once a year. You should replace the oil in the lower unit of saildrive, pull the prop and the anode (completely remove the anode), and clean the scale off of all sides of the anode (a Dremel with a cylindrical sanding drum works well). Scale will build up on the anode in both fresh and salt water. As the scale accumulates it will inhibit the effectiveness of anode and possibly lead to deterioration of other parts in the lower unit, which could be big time expense. If you are unfamiliar with Galvanic Corrosion do a Google search.

My trailer came with the boat and is an excellent trailer with tandem axles and 6 post supports in addition to the keel rest. It was manufactured by CMF Metal Fabricators LTD, 2975 Cote St. Charles, Hudson, Quebec, Canada JOP 1H0 according to the original papers. I don’t know if this company is still in business since the documentation I have is from 1984. The only fault I have with the trailer is that it only had brakes on two wheels. If you have a regular pick up truck with a 6,000 lbs capacity, brakes on two wheels is not enough for traveling over the road. I also changed the hitch where it attaches to the ball as I felt it did not have adequate strength and was getting old. If you send me your e-mail address I will send you pictures of my trailer. At our little marina we do not have crane facilities so I have made simple clamp or bolt on modifications (a tongue extension and keel guide) to the trailer which allow me to launch and recover the boat from a regular boat launching ramp. My address is mailto:wmabrock@msn.com"> color=#0000ffwmabrock@msn.com.

Hope this helps,

Bill

Just reading the manual now.  For the sensing element it states that the element can be tested by "short circuiting the connections 1 and 2 (refer to engine electrical diagram) on the red control box"

Jumping ahead in the manual to page 49 "Engine Electrical System", connection 1 is listed as "key switch" and 2 is "acoustic alarm".

Assuming this is correct (please tell me if otherwise), my understanding then would be that while this procedure tests if the alarm itself works, it doesn't actually check the membrane's integrity, correct?
