Preventative Maintenance Importance

Unread post by Gotofflucky »

Recently did a post concerning Honda 130 Impeller, and Silver Fox commented on the importance of PM checks, manufacturers recommendations, and shop manuals.
I could not agree more, my boat is 20 years old and new to me..looks fairly clean, seems to have had periodic maintenance completed by a shop, according to the previous owner, who had service records to back up his claim.
It was finally a nice day here today so I pulled the bottom leg off again and opened up the top of the engine to see if I could locate the thermostat cover, as I am planning to flush gunk outa the system and replace the thermostat when parts arrive. The two pics below, show 3 issues I discovered while casually looking and cleaning! Appears to be a bolt missing on a belt tensioner...not to be found anywhere? And other pic shows 2 hose barbs (Center portion of pic) with nothing on them, don’t ask me what they are for....I haven’t yet got my new shop manual which I am looking ordering as soon as I post this.

Anyone else find some “surprises” on your engines when just having a quick boo or clean?

Nice clean engine shows it was well cared for/serviced!

Sometimes there are fittings that look like they should have a hose attached but are intentionally left open to atmosphere. I cannot say if that's the case with the two in your second pic. Service manual should help with that. ;)

I have a full Honda shop manual on order! Once it arrives I will check out those hose barbs and belt tensioner....in the meantime I put a 6mm bolt in the tensioner, not sure I needed it though, I could not get the tensioner to move with moderate pressure.
So, before my new thermostat arrives next week, I pulled the old one. The previous owner told me he was religious about flushing the motor after salt use, and I believe him, but look at the gunk in there after 20 years use in salt despite flushing with fresh water!
I am now going to flush the whole system with a “de-scaler”. Lots of potential products/recipes on line, but I think I’ll go with vinegar/water/ Dawn dish soap first....seems relatively un-invasive while still helping.

While you are in there you should replace the 2 internal zincs as they are probably corroded down to nothing. One on each side in the water jackets and could be tuff to get out.

Thanks for the tip Elgavilan, I had checked all the external zincs, but did not realize there were two internal...I’ll be getting on that today.
