1987 Searay 300 Wiring Diagram

[Tony Mccusker]

Hi all,

Newbie here. I'm Tony and I am about to embark on fixing up a 1987 Searay 300. The boat came without engines, outdrives etc. and some of the wiring loom missing. I was hoping someone could help me with wiring diagrams for the boat as I have searched the net and I been unsuccessful finding any.

Thanks in advance,
Tony

Hi Tony,

I have some wiring diagrams for 1988 300. I don’t know what changed between the years, but if you want them I can send them to you. They are large files, so PM me your email address.

Hi Dan,

Thank you for the above. I have messaged you my email.

Thanks again, much appreciated.

I responded personally to Tony, but wanted to respond here too so others would see it and maybe help better than I did. Unfortunately, my schematics were for late 80s 310 and 340, not 300. Maybe someone out there has wiring diagrams for the 300.

I am struggling with the electrics on my sea Ray 220 there does not seem to be any power from the fully charged batteries getting to the dash panel. Am I missing a fuse box that is hidden somewhere?

Does it have a battery switch? Is it on? Don't mean to sound rude but I've done that a couple of times. Just today I realized the battery switch on my RV had been off for a week. No wonder the batteries were failing. I've done it a couple of times on my boat as well. Now when things don't work the first thing I check is the switch.

And of course the other possibility is a a fuse box close to the switch.

Yes I’ve got one of those three way battery switches that is bat 1 or bat 2 or both batteries or off. It’s on
Yesterday i had a breakthrough, I ran brand new positive and negative cables from battery and managed to light up the dash board again. I’m just ordering 40amp circuit breakers for the new cables.
I’m slowly getting there
Thanks for your input
