    Hey Mumbles, it looks like the thrust washer on this may be shot. In case the shop I’m heading to doesn’t have a washer, how thick should the delrin be for the washer?

    I can’t remember what I made them but if you put your starter back together and measure the end play, that will give you an idea of where to start. Without a diagram handy, I’m sure there’s a thin washer on top of the armature to. You gotta have some end play.

    I had a tussle with a V4 140hp omc last year,
    when I bought the powerhead in 2012 the starter seemed fine.
    then in storage till 2020

    last year the starter just barely turned the v4 over, even with full battery..
    eventually just tossed it and got another starter.. Took right off.

    oddly mine just went bad with time.. I still have it.. might dissect it at some point.

    Ok, so if you haven’t run into it yet, EvapoRust is a bit of a miracle worker for anyone that works with ferrous materials. Last time I picked some up it was about $30/gallon? Gentle enough to leave original 60+ year old paint in place, but still breaks the rust down and leaves bare metal. It is very slightly acidic to neutral (pH of 6.1-7,) this is good because shellac such as that on the windings can be wiped out by a base.

    So, I broke the starter down as much as possible. (as you can see in this post)
    Got as much of the loose rust out as possible, put it in a container and cover it with EvapoRust, I’ve got a cheap aluminum cooking pot that I usually use, but for odd shaped stuff you can use PVC with an end cap, or heat-seal some thick plastic sheeting or whatever works. Once it is covered, leave it soaking overnight at a minimum, 24hrs is usually recommended.
    Towards the end of the 24 hours I put the entire container in my ultrasonic cleaner. Its an amazing tool (if you don’t have one, look into buying one, largest one that you can afford/that fits on your bench) and let it run for about an hour.
    Afterwards I generally flush the EvapoRust off with hot water and inspect everything to make sure it took care of it all. If it looks good, clean and prep for paint or reassembly or whatever the next step is.

    You can then strain the EvapoRust and reuse it a few times before having to dump it out.
