    Older Evinrude Engine

    I have a tiller (pull start) 9.9 hp long shaft 2-stroke, circa 1976. Has been running well over the past 3 seasons, but this spring she's giving us problems. She's starting ok, it just that I'm only getting less than half the thrust (hp) out of her on the water. She runs fine in the barrel, but...

    Battery location

    This may be a dumb question. A small 12' aluminum open fishing boat. How close can a battery be to a carry-on 6 gal. gas tank? I would like to be able to run both the main engine (7.5 hp) and a 40# thrust electric, off the stern. With the gas tank near the engine (behind the rear seat, can I...

    Flex Fuel

    A new service station has opened up down the road from me. They offer the standard 3 grades of gas. They also have another pump on the side offering what they refer to as "FlexFuel", which is designated as being an E50somethingorother Ethanol product. The cost is about a nickle less than regular...

    2006 15 HP Yamaha

    Early this year I replaced the water pump. At that time, I noticed a heavy build-up of black, geasy gunk on the inside of the prop. I cleaned it all out using acetone, WD-40 and a pressure washer. Got it looking like brand new! I've got 30 hours on my engine right now. The gunk is back! :mad...

    15 HP, 4-stroke

    Hello gentlemen; this 2006 engine is running fine, but with the 15' boat, which I have it on now, I'm only pushing along at about 18 mph (GPS) with 2 of us on board. At WOT, the engine is turning about 5400 rpm's (which is high for this engine). What I'm looking for, is to - somehow - increase...

    Prop question....maintanence related

    After replacing my water pump (previous post) successfully, I noticed a build up of heavy, black, sticky, soot-like accumulation, had formed along the inside diameter of the prop and prop housing. The spacer behind the prop was also covered in this gunk. I used a bottle brush and some degreaser...

    First Water Pump

    2006 Yamaha 15 HP, 4-Stroke (EL). Bought the factory Service Manual and a full water pump replacement kit. The diagram in the "Lower Unit" section is exploded and fairly self explanatory. However, in speaking with some friends, they say that taking off the lower end and replacing it, can be...

    Gas Treatment during winter storage

    I have a Yamaha 15 HP, 4-stroke. It's 3 years old now and each year I did not run the carburetor dry. This year, it was suggested, by my marina, to put a fuel additive in the gas (ethanol enhanced) and run it several times to insure the additive is in the carb, before putting it to bed for the...

    Cost effective approach?

    ....to increasing an engine's horse power? I have a 2006 15 HP electric start outboard that I want to add some umph to. My boat is rated for 35 HP, so I've got a ways to go....if it's practical?

    2006 Yamaha 15 HP outboard - carb

    Bought this engine brand new in 2006 and have used it during the open water season, here in MA, each of those years, including this one. Spring of 2007 I installed a water separator (10 mc Yama filter). I usually disconnect the portable tank each winter and use the residual fuel in my...

    Top End Speed Problem

    A quick summary of my problem: Three years ago I purchased a 14' Crestliner Sportsman tiller fishing boat (rated for 35 HP) with a 15 HP Yamaha, due to lake restrictions. I was disappointed with the top end speed (16 mph), so the marina swapped me the 11" pitch (3 blade) standard duty prop, for...

    Charging Batts in Storage

    When I pulled my batteries (2) out of my boat to store in the basement, I charged them full with a 15 amp charger. I repeated this in Dec. - just prior to the holidays. No problem. I just put the charger on them again yesterday, wherein my problem has occured. The first battery is my starting...

    Jack Plate Installation

    Earlier in 2007 I posted about a top end speed problem (lost speed) I was having with my 15 hp Yamaha, once I installed a Doel Fin on the cavitation plate. From the feed back here, I've purchased a "Mini Jacker" jackplate to attach to my transom; in order to give me the adjustment I'll need in...

    Used jack plates

    I'm looking to put a manual jack plate on my boat this coming spring, before putting her back in the water again. I was told, by a member on another fishing forum, that there is a place to go, here on the net, for "used" jack plates. I am trying to hold down cost, so I would be interested in...

    Top End Speed

    I am new to this site, so I hope this is the right place to ask my question. I have a one year old Yamaha 15 HP 4-stroke engine on a Crestliner 14' Sportsman tiller boat, also a year old, both bought new in 2006. My engine came with an 11" pitch prop which I quickly swapped with a 9" prop to...
