    Tiki Pontoon with 80hp mariner - prop selection?'s

    Boat in the picture ? I built this boat a few years ago It has 4 pontoons 2-25? toons on the outside and two 20? toons on the inside. I first threw an old 40hp Johnson on it that ran awful. Then I bought a 1980 80hp mariner but there were carb issues and lower unit issues that prevented me from...

    1988 20hp mariner dies at mid range throttle when warm

    This motor ran perfect when I put it away for the winter. Took it out this year and it seemed to run perfect but after 10-15min at moderate to full power it started acting up. Once it starts doing this it will still idle in or out of gear perfectly. Out of gear it will rev up seemingly fine. Rev...

    1980 80hp jumping in and out of gear when in forward

    When you put the engine is operated on a hose it runs perfect. Then when you put a load on it in forward (Aka when it is in the water) its like the sliding clutch is jumping on the forward gear. It idles fine in gear but with the application of much power it starts jumping. This is violent and...

    1980 80hp Outdrive Reassembly

    I was getting some water in my outdrive oil so I pulled everything apart. I didn't really see anything that looked bad upon disassembly. Seals didn't look to be in great condition though. Gears all looked good and the bearings are as well. They aren't brand new but they will certainly do. I went...

    where to find starter brushes 1989- 20hp

    The brushes are shot on this starter and all I can find is the SR367 part which is the end casting with brush assemblies. I believe the starter is referenced as PN 5367 and was used on most all of the <25hp mercury and mariner starters up to 2003. I cannot imagine that nobody sells just the...

    Volvo sx drive ss prop selection

    Long story short we have finally decided to go stainless after spending way to much time and money having dings and bent blades repaired on aluminum props. The boat is a 2000 four winns horizon 180 with the volvo 5.0 GL engine with sx outdrive. It is used primarily for watersports as well as...

    1980 80hp - hard misfire

    It is a 80hp 4 cylinder 2 stroke. I finally got this thing running and it ran good for 20 minutes and then developed a misfire. It runs fairly good at idle and will rev up and sounds strong in neutral but under load it has a hard and consistent misfire. It feels like I'm hitting a large rock or...

    1980 80hp mariner lower unit oil seals - oil

    I just got the motor running (carb issues) and after tuning it on the stand / hose the next morning I noticed some oil under the prop. I pulled the prop and the seals directly behind the prop on the shaft do not look to be leaking at all. However there was a lot of water / oily buildup in whole...

    aluminum or stainless and to repair or not to repair

    Hey all, we have a 2000 four winns with a volvo 5.0 and I believe it is their sx drive. The boat is used in the Maumee river ohio which is a fairly shallow body of water with a thick muck bottom. We keep the boat docked at our house and so we have to go about 1/2 a mile through a channel to get...

    1981 mariner 80 will not idle / run

    The motor has 120 psi in all four holes, good strong spark with new plugs, I went through and cleaned both the carbs and it looked like they had very recently been rebuilt anyways. Trouble is it will not start with the throttle at idle it doesn't even hardly try to fire if I push the throttle to...

    electrical problems preventing spark - I'm stumped

    I have a 1981 80hp 4 cylinder mariner. The engine cranks over just fine but has no spark. The first thing I did was remove the Black / yellow wire off of the cdi unit and sure enough it cranks over, produces spark and fires right up. Then as soon as you touch the black / yellow wire to its post...

    1965 johnson 40hp what are my options (heavy boat)

    I have built a 24 foot quadtoon tiki boat (two 25 foot toons on the outside and 2 20 foot toons on the inside, see picture). I picked up 1965 40hp Johnson for it. I am not trying to go fast just trying to push it along. This boat does not like to move along through that water I can just tell...

    Can someone Identify this rack and pinion steering cable

    A buddy called me up yesterday saying that the boat he bought last week steered really stiff. I sort of figured it was the steering cable and sure enough it was. We removed the cable entirely out of the boat put it as straight as could be and it still took loads of force to get it to move. The...

    1999 four winns floor soft spot

    I am the third owner of a 1999 four winns horizon 190. Ever since I bought the boat 3 years ago i have noticed a soft spot in the floor. It is right in front of the engine compartment and just about to the ski locker. Basically it is the area above the gas tank on this boat. Is there any type of...

    5.0 gl valve lash adjustment

    I will try to keep this as short as possible. I have a 5.0 gl volvo penta engine with an sx outdrive. We ran into a problem last years that necessitated pulling the heads off. So we did that and got everything back together and she seemed to be running alright out of the water. After we put it...
