    Question re: WH-40 jets

    Hi, I'm cleaning my WH-40 carbs in '87 XR-2, and I noticed in the bottom carburetor one of the main jets was missing. The jets are 0.78. Would there be a mod reason a PO may have left out a main jet? I've had the engine for a few years and has always run fine other than sitting up past 2 years...

    Is it safe to backflush an outboard?

    Greetings, I have an '87 Black Max 150 HP and have a Sterndrive Engineering lower unit (have used it 5 years with no issues). I recently changed the impeller as routine maintenance, but am concerned about high water pressure at idle and higher RPMs. At idle on the muffs at 1000 RPM, I'm...

    Quick thoughts on old Starcraft?

    I have someone local really trying to unload a '71 Starcraft with a Johnson 115 in a hurry. Other than the fact that craigslist is the wild wild west and a buyer might not want to go by himself when dealing with a desperate seller (the asking price has gone from 1800 down to 1400 down to 800...

    Question re: single axle carrying weight, inner tire wear

    Greetings! I have a single axle Magic Tilt Trailer currently carrying a 20.6 Larson bowrider with a Merc V-6 outboard. The dry weight of the boat is listed at 1800 lbs, so I figure with the engine and fuel I'm well exceeding the carrying weight of 2000 pounds noted on the trailer ID. I...

    Question re: '87 XR-2 150 HP high water pressure at idle

    Greetings, I have a '87 Black Max XR-2 150 HP. I had a leaking poppet valve and just replaced the poppet internals, thermostats (with OEM 143F ones), and impeller. I have had the engine for 3 years and it has always ran strong. The problem is that when idling on the muffs, it now has 12 PSI...

    Question about Lake Wissota, Wi? water coloration

    I was recently visited Wisconsin and did some swimming at Lake Wissota, and also Lake Holcombe in N Wisc. I noticed that both lakes have an almost "root beer" type color that seems distinctly different from the lakes in South Carolina that I am accustomed to. Does anyone know the reason for...

    Social Media Etiquette on the lake?

    Do any of you boat with facebook people? The reason that I ask is that I have noticed a somewhat mildly annoying phenomenon since about 2009 when taking friends/groups of 3 or more on the lake: It never seems to fail that several of the people invariably are more preoccupied with taking...

    Rack steering: NFB vs standard?

    I have read a fair amount on this topic using the search function, but have a unique situation on my hands in the choice between the two: I have a 21 ft Larson Bowrider (2002) with a 1987 Black Max XR-2 150 HP V6 with standard rack steering with a tilt helm. The steering is a single cable...

    question about trim motor up/down

    Hi, I have a '87 115 with the Integral trim system. I replaced the pump about 2 seasons ago. The fluid level is topped off with ATF. The problem is that it will trim all the way out to the trim limit from the all the way in position, but will not tilt up, or trim back in. When pressing...

    Question about ATF in Integral trim system

    Greetings, I have a 1987 Black Max 150 HP with the Integral trim system. The manual calls for Type A or Type AF ATF. The possible problem is that I put Castrol Type F in it instead before realizing my possible mistake? It has worked though, just don't want to mess up any O-rings or seals if...

    Hi, I am soon to be putting the top cap back on my 2002 Larson 21 foot OB model after pouring the Arjay transom. Originally, the top cap/hull joints contact points in the bow floor area and splashwell to transom area had a rock hard type sealant that had to cut/chiseled when I separated the...

    Hi, I completed pouring my transom last night with Arjay 6011 and used MEKP-925 at the catalyst. I am going to update an earlier thread on this later today or tomorrow and share what I learned in the process. In short, Arjay 6011 is incredibly easy to pour and is a GREAT PRODUCT for ease of...
