Your motor has spent time in the southern US, your bug is a type of wasp known as a mud or dirt dauber. They make mud "nests" in protected places that they lay an egg in then fill with spiders for the larvae to eat when the egg hatches.
Just check on the internet and that looks exactly like what it was, thank you. I’m in Saskatchewan and never seen them before. Was told the boat came from Ontario. Thanks for the comment, now I know.
not really, getting ready to go over an inherited 115hp that has sat for 10 years, will be looking at a lot of videos as I run across problems.@@andysangels1970
I’m so happy I found your channel I have the same model of motor that needs work It’s nice to find videos on this motor that’s not 10 or year older Please let me know if I can pick your brain on some upcoming repairs Thanks
That’s honestly pretty darn good for a 17’ fiberglass. I’m currently tuning up my dad’s fishing boat with a Mariner 75. Looking forward to seeing what I can get out of it.
You should ground the tester to the Block, using a Plug adds a 2nd Gap to the Path. It is recommended that both Switchboxes are replaced when one fails, has to do with a Bias between the two My 84 115 still had the Factory Plugs in it when I traded it 14 yrs later with 800 hours on them If the Head Waterjacket cover leaks water, it is likely warped due to overheating, which happens on these from over trimming the motor Don't fiddle with the Linkages without the Service Manual, the throttle valves don't open until all the Timing is in
My thought of testing to the plugs were to ensure equal spark to each of them and knowing that grounding wasn’t the issue with the spark in the first place. I also see how grounding straight to the block though would be best for a final spark test as it would be more accurate. The spark seems fine now with just the one switch box replace. If they were cheaper I’d do both. If a fault came from higher above causing the box to fail I would expect potential damage to the other. With just normal wear I’m unsure how one would affect the other. Not saying you’re wrong but I honestly can’t see that because they are separate of each other. I will look more in to that though. And which linkages? Like the throttle to the timing? I appreciate the comments, it’s good to hear from someone else who has worked with these motors.
Interesting. I do have the original manual with the serial number. When I looked it up online all searches came up as 86. This boat was originally purchased in Ontario. From what I could find is Canada got a different “style” that year. Possible they gave Canada the old look on the new motors to use up parts?
@@MrKattlyn2 No. I was at a Dealership in Western Canada in 84, 85, and 86, and 84 and 85 were the only 2 yrs of the Brown Cowls. Does the Serial # on the disk on the Block, match the # on the Transom Bracket? I guess someone may have put a 84/85 Cowl on an 86, why I don't know. I took the Brown One off of my 84 and replaced with one from a 1971 1150. Red Decal Cowls were the Best ones Mercury ever had.
enjoyed the video!That is a nice motor as well. Plus sweet child o'mine is playing when he is doing timing!!

We have a ton of those here in Georgia. I’m actually working on that exact motor right now. I’m having trim issues. Any way you could help?
@@andysangels1970 what is going on with your trim? I could try to help.

Im from Mississippi in the US.I fight those all the time with my outboard
I’m so happy I found your channel
I have the same model of motor that needs work
It’s nice to find videos on this motor that’s not 10 or year older
Please let me know if I can pick your brain on some upcoming repairs
Thanks
@@danadreger953 absolutely you can
I own a 1975 version of that motor; your's sounds a lot smoother!! Powerful motor, nonetheless.
It is a great motor. They did change quite a bit over 10 years so no doubt it sounds a bit better. And I’m very impressed with the power so far.
Bug is a mud dabber which is like a wasp and make the mud nest you seen from dirt
That seems to be the general census. Glad we don’t have them here, they seem like would cause a lot of unnecessary issues
@@MrKattlyn2 video is very good. Thanks for making!
They call them mud dobbers here in Oklahoma they are kinda like a wasp.
Thanks that seems to be the general census. I can imagine they cause a few issues with their nests
My 17' Crestliner (fiberglass hull) tops out at 32 mph with the '75 .

Brown Stripes on the Cowl were used in 84 and 85, in 86 the Stripes were different

Very interesting. Well I have the boat in storage. I will certainly check that out when I get it home in April.
Dirt dobber nest bro
Seems to be the census. So glad they aren’t a regular problem here. I’d imagine they are nuisance at times.
