Tune up on 115 Yamaha 4 stroke

9 posts in this topic

Hey Valv or any of you marine guys.

I need a tune up on my motor. 115 Yamaha 4 stroke. I do all the oils etc. myself. What can I expect to have the shop do if I did all the oils and plugs?

What all is there to do? Valvs and Synchronize carb?

What else should I have them look at when its in?

Thanks guys you are a great help to many of us who lack in the mechanics ability.

Northlander,

There should not be much more to do, other then change your fuel filter and lower unit grease. Also grease any zerts that you can find.

Hey Northlander,

I have the same motor, may I ask why you feel you need a tune up? My thoughts are the reasons for needing the tune should steer the shop in the right direction (poor idling, loss of top end RPMs, etc.) should help them with what to look at first.

I'm asking because I'm going on year 5 and wondered if I should do anything else, clean the fuel injectors? Check some of the gaskets? All is running perfectly, but thinking of preventative maintenance.

Thanks

Chris

I am being told by a few that the impeller should be changed every other year or so. I am still debating about doing it myself cause the cost of this is about $150

cjac I have been told by a few friends with the same motor and by the shop that with as many hours as I put on my boat its time to have the valves checked out and synchronize the carb. My motor is a 03. I have no issues with my motor at all.

I change oil/filter, lower unit done and new plugs as well as grease zerts twice a year. Like I say my boats on the water every almost daily and I do a lot of runnin. May be overkill but I see it as a cheap way to make sure its always runnin. I hate it when I cant go fishin.

I believe your motor is an EFI so you wouldn't have carbs to sync.

Some earlier F115's were carbeurated but they have been efi for the last 5 years or so. They do need to have the valves shimmed though after 2-300 hours or so. At least Yamaha recommends this. That won't be a cheap deal though. Its a pretty complex job. Good luck.

I have owned two Yamaha 115s a "01" and now a "04" and can see no reason to be doing any major motor work if the engine is running well. confused.gif

I got some dirty gas last summer and had major problems with plugged injectors and filters though! mad.gif

Had to have my injector screens cleaned two times and finally another in-line car type fuel filter installed. That took care of my problems! laugh.gif

      We struggled on walleye on Frazer bay this saturday, so sunday morning I started throwing senkos.  Not quite consecutive casts like Wanderer, but i went all morning catching nothing, then caught these two cousins with 3 min of each other, smallie off the point, then the big mouth around the corner in a shallow bay.  18" smallie, 17" LMB. Good fun.    We did get about a dozen walleye on sunday night after the storms chased 15 boats away from the point we were fishing.  Mostly small, but a couple keepers.  Chartruese Jig and rainbows in about 10-12 FOW.  Couldn't buy a bite with a chub.

      I have good Jeremy how have you been doing. I need to get out fishing with you soon.

      Stick in the Mud   I do think sometimes that those fish see so many jigs and shiners that something such as a crawler or leech is a great change up and will get bites.  Also with the bug hatches that are happening, those are two great baits.       Leech Lake   Leech Lake Walleyes once again found themselves spread out and in different areas and related to different pieces of Leech Lake structure.  Shiners and Leeches seemed to be the bait of choice for those Leech Lake Walleyes, but plastics are still catching some fish.  Be sure to stop in at Full Stringer Bait and Tackle, Swansons Bait and Tackle, Tutts Bait and Tackle, or Sportland Bait and Tackle for all your bait and tackle needs.     West End The LOA Fishing Guides found much of their success on the West End of Leech Lake.  Focusing in on the flats around West Goose in depths of 7-10ft of water, as well as the wind blown points such as Duck, Big Hardwoods, Ottertail, Pine, and Bowmans.  Sucker Bay also proved to have a good wind driven bite throughout the weekend.   A Jig and Minnow was the best presentation by far, but in most instances instead of jigging it, dragging or swimming it along the bottom seemed to work best, but when the front came in on Sunday the Leech Lake Walleyes were snapping and aggressively jigging was provoking the bite.  When things slowed down, slowing down with a lindy rig and leech put fish in the boat as well.  Green cabbage once again was a key to finding active walleyes and jumbo perch in 5-8ft of water.  Pitching an 1/8th oz KenKatch jig with a shiner caught Leech Lake Jumbos, Walleyes, and pike.  Slip bobbers and leeches/shiners also have put fish in the boat being either fished in the weeds or windblown points.   East End/Main Lake On the Main Lake, the rocks still were producing a great bite as well as some of the East End points such as Battle, Sugar, and Five Mile when the strong Westerly winds were blowing.  Annex, Submarine, Pelican, and North Bar were all producing fish in 10-14ft of water. Lindy Rigs with leeches or shiners seemed to work best, but the biggest fish still seem to want a 1/8th or 1/4oz jig and shiner.  
      Leech Lake Crappie and Bluegill fishing still remains strong.  When the weather warms up for a couple days both species are moving onto their beds and are actively feeding.  Looking to Boy Bay, Millers Bay, Shingobee, and Steamboat for the best action in 3-6 feet of water.  Just remember to use selective harvest as these fish are more vulnerable.

      Memorial Weekend,      Hit Waconia Saturday morning for bass. Caught about 40 largemouth--most from 14 to 17 inches, with a few 17 and 18 inchers--and several nice pike. Fish were in cabbage out from bedding areas, in about 6 to 9 feet of water. Fish were scattered, lying in the weeds looking up for sunfish that are staging in these areas preparing to move in and bed. With this situation, we buzzed spinnerbaits and weedless spoons over and through the tops of the weeds, and the bass aggressively came up on them, as well as some pike. Had one lazy muskie follow as well. Got good footage for a bass segment of Fishing and Hunting the North Country on You Tube. Added footage of a couple smallies from out in the Hutch area Saturday evening. The bass fishing will continue to get better as the water warms, with more big ones, and the sunfish bedding bite is probably only a week or less away. Good luck, and I will see you out there somewhere.

      Memorial Weekend,      Out on Washington Saturday afternoon and evening after hitting Waconia for bass Saturday morning. Caught largemouth, smallmouth, and pike. Added footage of a couple smallies to the largemouth and pike footage from Waconia for a bass segment of Fishing and Hunting the North Country on You Tube. Caught the bass and pike on Washington in four to seven feet of water, out from bedding areas, on spinnerbaits, Rippin' Raps, and Shadow Raps. Up on Mille Lacs this coming weekend for a walleye tournament, then will be back out in the Hutch area the next weekend guiding. We were targeting bass this weekend, but got a tip that walleyes are biting on a couple Hutch area lakes on live bait. Good luck, and I will see you out there somewhere.

      Geez Terry! Now you will be telling me that walleyes are only good muskie bait! Cliff

      Nice report Cret Musta been a thrill getting that 9.75 Gill.

      Wow dude lol Sup Moose how you been?

      Vermilion has excellent fishing for both bass species   The east end has the best Smallmouth action and the west end has the best Largemouth action, however you can catch either on both sides of the lake.  For Smallmouth, rocks, docks, points, saddles, reeds, wood and the shoreline rubble are all very productive. Most of the green bass are found in or near the slop and the west end has the best of what they like the most. Spinnerbaits, any color as long as it's white, stick baits, cranks, topwaters, jigs, swim baits and soft plastics all work for Smallies. Jigs, topwaters(Frogs) plastics and a host of other stuff will catch the green bass. Have a great time, the midweek traffic is very minimal.   "Ace"   "It's just fishing man"

      Bla bla bla, all this Walleye talk is boring me to death.   The real opening day is this Saturday when the Muskie opener comes to Minnesota and the Big V.  I'll be out fishing with my son and grandson searching for some real fish.   The weather looks great, my baits are all sharpened and the new line is on all my rigs. Bucktails, Glittertails, spinnerbaits and minnow style cranks will make up most of our arsenal, however we will also be tossing a few topwaters looking for those Big green girls and not even talking about Walleye fishing.   Have a great weekend everybody!   "Ace" "It's just fishing man"
