Starting after a long storage

[Motomanmatt]

Purchase a 58 Evinrude 7.5 out of an estate. Looks brand new. And had a tag that it was winterized in 1995! Motor is clean as a whistle. I’d like to start it but I want to make sure I do it the right way. Any tips? Thanks in advance. Matt

New Impeller, check gear lube, and fuel hoses.

Prepare to be boarded!

it may be  wise to  also  clean the carb  should any  problems develop.       who knows how it was stored.

for simple winter  lay-aways   I always store  fully fueled  (carb  filled)  with fuel conditionner  circulated in

for long term I would always run it dry  to prevent  dried fuel deposits

ignition coils may be  badly cracked  but easy to replace  condensers likley  bad to … all normal stuf with lots of help here !!!  and  utubes

changing impeller  requires PH  removal   sounds complicated but isn’t…see lik on  impeller change by pulling the drive shaft from the GC

so it depends… as they say

great engines btw  take care of  it  and it will take care of you 🙂   great refurbish project !!

lots of utubes…if you don’t have a tank you can convert to single line  tank

timing will need to be set…see video

I’m so envious!  Even though the engine is new/never been used, it is likely that the coils have failed/cracked.  You can inspect them fairly easily by removing the recoil and the little inspection cover over the flywheel.  Like everyone says, gear lube, water pump impeller, ignition service.

The important thing to remember about this engine is that is must be mixed at 16:1….  Ignore all the hype about today’s oils being better, which they surely are.  But, this engine has plain rod bearings that need all the lube they can get, or they will prematurely wear/fail.  The beauty of these engines is that when properly tuned, they hardly smoke at all, even at 16:1…  Do you have a pressure tank for it?

Pleasee let me know if you have any questions or need any pieces/parts, I have a basement full of these 58s.  Don

Thanks for all the helpful tips! I’m a bit of a newbie to outboard motors. Been tinkering on vintage motorcycles and British sports cars for 40 years, so this is new! But so far I’m loving it – and all the support that is available, like this forum!

I converted the motor to a single (modern) fuel line and pump last week. I bought a new impeller and hope to put that in on Monday. Bought some lower lube and will top that up on Monday also. And from my research it looks like I should just go ahead and install new coils – ordered them today!

I only have one photo right now, but will post more!

Thanks again.

Sorry for the double post. Must’ve accidentally clicked Submit twice.

beautifull engine… do change your plug wires with metallic core ones  . you can reuse the boots if ok  the impeller is tricky has stated but not difficult

I have  used  Belden metallic automotive wires  with boots ..but 4  feet is cheaper

capacitors  likely needs replacement see great articles from MR Mohat

Super helpful advice – thanks!

 

PS As promised, a few more photos. It really is remarkable how clean this motor is – it’s hard to tell it ever ran! (The only thing missing when I bought it was the starter mechanism. As you can see from the different color, I found one online. 😉 )
