Hi,

G2 200HP HO.  Engine serial number 05509579.

Port engine trim decided to trim all the way up whilst running all by itself.  The trim motor was stuck running.  After a few mins the trim motor stopped.  Now the engine is stuck up and none of the trim buttons work now, control box nor engine.  

Reading other threads it sounds like it might be the trim relay and possibly now the motor has burned out.  

Can I ask if there is anyway to bypass the relay if it is that?  I know I can manually drop the engine but then how can I get it back up?  Just wondering how we can keep running whilst waiting for parts.  Having the motor trimmed fully down will be pretty tricky as we operate in some shallow water.

Many thanks,

Tony

This is about the 4th time I have heard this happening. Keen to find out what is the root cause.

I wonder how many of the relays, sensors,  and electrical issues originate in China?  Not just with Etecs but other OBs also.  My dealer before hurricane Michael blew him away was also a yamaha dealer.  He told me the biggest issues he has with either brand is usually sensor or relay related.

T/T relays have been failing for 50 years+, back in the good old days where everything was Made in the USA.
High current flows, high voltage inductive kickback, salt water environment, salt deposits buildup in T/T joints all add to overstressing of the T/T relay.  Most motors do not have enough room under the cowling to put a unit in that will have contacts that can withstand the overstress.  Even the best silver alloy contacts breakdown in overcurrent overvoltage situations.

Where are those located?
Are there 2, one for up and one for down and u swapped them to get it sorted out then got a new one?
thx

Hi,

Just 1 per engine.  Our dealer had one in stock so he came and fitted the new one.  Very simple job so probably a useful spare part to carry.

Cheers,

Tony

Tell me I'm wrong please or did BRP really screw up on the G2 3.4s

E. site shows 0586767 cable and relay assembly, T&T for the G2 3.4s

This same relay module was used in the G1 40hp 2 cyl units as T&T.

Is it really that HD?

At least it's an easy Plug and Play replacement.

There are others way more knowledgeable, but I'm thinking a Relay only transfers the power - similar to a solenoid, except it goes 2 ways?  Get the juice turned on, which then gets way more juice turned on to run the T/T motor?

Surely could be the same one, I'd guess?

EDIT:  Are the mounting bolt patterns the same?  Passing the same current?  We could just use this one...

Phil

The tilt/trim motor drives a hydraulic pump. The output force of a pump can be greatly increased by changing the size of the cylinders that it drives without increasing pump load so the trim motor could be the same size across all engine models.
40 hp is a single piston unit while the larger engines are 3 piston units.
The tilt trim relay unit looks to be the same as the two 30 amp relays that have been used for many years. Phil, the output of one relay is grounded in the off position (in standard Bosch terminal numbers 86A to 30) and connected to power from the battery cable (87 to 30) in the on position.
Blue trim motor lead to one relay and green motor lead to other relay. Relay 1 on and relay 2 off puts power to blue wire and ground to green wire for trim up. Relay 1 off and relay 2 off keeps blue wire grounded and puts power to the green wire, down trim.
While I'm in educator mode, the starter relay is a single contact relay and each trim relay is a double contact unit. Now for the technical stuff. A relay uses an electromagnet to change an electrical output. A solenoid uses an electromagnet to change a mechanical output, so technically it is a starter relay. On many starter motors the starter solenoid was mounted on the starter motor and gave a mechanical output to kick the drive gear out, it also contained relay contacts at the rear of the unit which gave an electrical output to run the motor once the gear was engaged. An example of a true solenoid was the old outboard choke solenoid which when energized pulled the choke closed.
