    Reducing trolling speed

    Hi, I have a 19' bowrider with a 4.3lx mercruiser Alpha 1 outdrive. The current prop works great for water sports and cruising. It is a 4 blade aluminum Solas 14x21 prop. I would also like to do some fishing trolling with the boat and I was thinking of picking up a prop that would be used...

    WOT RPM for 4.3lx mercruiser?

    Hi, I picked up a nice used boat and just spent a week on the water with it. It is a 19' Cobia bowrider. What is the recommended WOT rpm for the 4.3lx mercruiser? The boat is in great shape and came with two new props. They are AL 4-blade solas 14x21 props. Without knowing the recommended...

    1991 198es

    We just purchased a very well taken care of 1991 198ES. The previous two owners have done a great job maintaining, repairing and documenting over the years. The engine is was replaced in late 2000 with a new engine/outdrive. The boat has a Mercruiser 4.3lx (4 barrel carb) and it runs like...

    1982 v150 excessive smoke

    Compression is good and even across all cylinders (118-120). Carbs are clean and fuel is good. When running on the muffs, I see much more smoke than I like. It isn't the typical blueish 2-stroke exhaust. The smoke is whitish/greyish. Give it a quick throttle and you get a fresh batch of...

    1982 v150: white exhaust smoke

    The last time I had this engine running on muffs, I noticed that the exhaust was more "whiteish" than I previously noted (much more actually). Compression checks out ok on the engine (117 to 120 on all six). I am guessing that this is a gasket issue or, worse, a corrosion issue that is...

    need help finding float or carb kit

    I have a 1982 v150 6010145. I have looked at iboats and I have looked at Napa. I can't find carb parts for this engine. It seems like parts for 1980-1982 aren't available. Another question, I have access to a 1984 v150. If I can't find parts, can I move the carbs from the 1984 to the 1982...

    head gasket question

    If a head gasket was starting to fail (not a major failure, but a small breach), would this show up in a compression test? I am getting some water vapor in my exhaust and I don't know if it is coming from the head or a gasket failure in the exhaust system somewhere. Compression is 118-120...

    Bad Stator characteristics

    I'm trying to track down a gremlin in my 1982 v150 ignition system. While looking through old topics, I see lots of "stator" issues or replacements. I see the tests that can be performed for the stator. In general terms, what are typical symptoms of a failing stator? Thanks, Dan

    Ignition part questions - for a 1982 V150

    What does a rectifier do????? I understand that a stator generates electricity, the trigger tells when to fire a cylinder, and the switchbox does the old distributor work (I think). What does the rectifier do? What is the bias circuit between the two switchboxes? Thanks in advance for...

    v150 stator and trigger pieces

    How do you know if these parts are bad? I guessing that with these parts, it is an "it works" or it doesn't work situation.

    1982 Merc v150 6010145

    I am losing spark in two cylinders intermittently. Never seems to lose both at the same time, but it is hard to tell. Looking at the engine from the behind the boat, the problem is with the top two cylinders on the starboard side. The problem started about on the last trip out. At the...

    De-Carb with the second fuel tank??

    I do the de-carb thing once per year. It just dawned on me (I'm not always the sharpest knife in the drawer) that I have a second fuel tank on my boat that I never use. My boat has two 36 gallon fuel cells. I use port tank nearly all of the time because that balance the boat if I'm out alone...

    carb model for 1982 v150 and carb rebuild question

    I plan to rebuild my carbs on my 1982 v150. I see on the iboats site, that these engines had different models of carbs. Is the carb model number stamped on the carb somewhere? I have rebuilt carbs on smaller merc (a 50 and an 80). Is rebuilding the carbs on the 150 any more difficult? It...

    I have one: a 1978 Penn Yan Explorer Outboard

    Purchased this boat used approximately one and half years ago. The boat is a 1978 Penn Yan Explorer (outboard version). There weren't that many of these boats. I am in the process of slowly restoring it. It currently has a wide open cockpit. I don't know what the original seating...

    1982 150 poppet valve questions

    ser 6010145 I want to replace my poppet valve and after looking at it, I have a couple of questions. 1) My Seloc manual has no section on maintenance for this part. Am I missing it somewhere? 2) While the serial number on my engine indicates that it is a 1982 engine, the poppet valve...

    Refurbished/Rebuilt outboards

    I plan to re-power my project boat over the winter. I would like reliable power, but I don't want to spend the money for a new engine on this boat ( a 20' 1978 Penn Yan Explorer - outboard). The boat currently has a 1982 Merc 150 on it and it is a good match for this boat (cruise 25 mph, WOT...

    Fuel/water separator

    I have a very common model of fuel filter/water separator on my boat. Unfortunately, it is not one of the clear bowl types. In this case, how do I know when/if there is any water in there??? As it is, I just change it once per month since the filter is not very expensive.
