VZ150 Starter Relay

[lsukevinc]

I had off the week between Christmas and New Years and I determined to hit the water. I pulled my boat out to start the motor on the ears and when I turned the switch, all I got was a click from the starter/solenoid. I removed it and bench tested it and sure enough it would only click and not engage. We were hit here pretty bad after the flood and most of the Yamaha shops are still closed due to re modeling. So I headed to O'rileys and bought a regular automotive solenoid and wired it up. For now it works great, but I did order a replacement one off of ebay. I'm going to try an aftermarket one instead of a Yamaha one due to the big difference in cost. i'll update the post if I have trouble with the aftermarket replacement.

That's what I don't understand: to have expensive outboard and cheap on replacement parts for it.

amahoeck.
do you have a clue what the words"ignition protected means ?????????

[amahaork]

I think it has something to do when gasoline vapor goes ka-boom in a presence of electric spark (besides from spark plug)?

[rodbolt17]

pretty much.
that ign protected has NOTHING to do with engine ign system.
it is also why marine parts get rated differently.
last fall I had a mercruiser in for repairs.
the owners had tried themselves.
the tag on the "replaced new" pump stated.
NOT for use in aircraft or marine.
the original steel tube from the pump to the carb had been cut and rubber hose with worm clamps installed.
the oil pressure switch that controls the pump had been bypassed.

when I asked the customer about it, he said we read it on the internet.

anyway I replaced all the non conforming parts,did a carb job and sent them on their way.

moral of the story: ya just cannot randomly do stuuupeed stuff.

there is rarely a reason to reengineer motors.

what is funny is the OP appearently does not realize that his motor has a starter relay AND a starter solenoid.
it is refered to as a master/slave setup.

thanks for the insult. I know there is a relay and solenoid, I can read. Oh and by the way if you go to the parts breakdown on boats.net the part I need to replace is labeled a relay by Yamaha (68V-8194A-00-00). But I called it a solenoid.

I thought everything on the internet is true though, you can't lie on the internet.

Chuck, what you have posted is the truth. Unfortunately it is not the whole truth. You have over looked a very important section of the CFR. None of what is written in CFR 183.400 applies to an outboard power boat.

Many miss a very important part. See below:

Yes, Agreed! However, my reason for posting this is for a general definition of what "ignition protection" is defined as.

Outboard boat motor manufacturers are regulated by what regulating authority? My starter relay is "ignition protected" Not only is it sealed with a gasket, it also has extended bands of metal for what may be heat sinks to remove heat from the assembly?

There have been several posts in this forum that have "fires" within the engine and even top cowl explosions where the cowl has blown off the engine.

In an earlier post I made, I suggested a winch reversing relay to replace a Yamaha tilt/trim relay. Now that I think about it, I rescind this suggestion.

Safety and "common sense" should utmost in considering alternative parts/methods. Although the US Coast Guard Boatbuilder's Handbook does not regulate outboard motor boats, and for that matter not any boats over 20 feet in length, it is a great reference for safety on any boat.

[cpostis]

Checking/confirming on my statement "not any boats over 20 feet in length" I recall reading that earlier, but may be in another section of the handbook.

In checking, Subpart I does not state "not any boats over 20 feet in length". Depending on what Subpart of the Handbook, different "Applicability" for each subpart is referenced.

[boscoe99]

It is appreciated that you took the time to explain what is meant by ignition protection.

Just wanted to make sure that readers that come along later don't read any of this thread to mean that ignition protected parts are required to be used in an outboard motor. All too many read parts of the CFR's and take them for what is written in that part. They fail to realize there is an applicability section that governs if the words apply or don't apply.

Same with ABYC and NMMA. People read what they say and take it as the gospel without realizing that these two organizations can only offer suggestions. What they say is not the law.

I think if you keep digging about there are some other rules pertaining to hulls with built in fuel tanks as well.
while the parts on the actual motor typically do not have to be ign protected I sure would want them.
same as when the fuel fill;vent ir sender leaks.
I sure would want all my below deck stuff to be ign protected.
I have actually seen bilge pumps pump raw gas when a tank leaked.
