    power head / exhaust connection

    What type of leak protection is there between the power head and the lower unit in regards to the exhaust. Is it a gasket like those used with exhaust header gaskets on automotive engines? Reason I ask, I believe I've got an exhaust leak once my engine has been run at WOT for over 10 minutes...

    Oil tank reservoir removed...how to check for oil pressure?

    Previous owner had oil tank removed and just run mixed gas. Motor is a 1996 Mariner 115 and want to determine if oil is getting to upper main bearing. I found 2 sets of lines, one apparently sends fuel from the enrichner valve to the back part of each cylinder (don't quite know why) and the...

    Motor squeaks when hot...inputs?

    My motor usually runs like a champ but when it is throttled back to idle after running WOT for a few minutes, it sounds like it is squeaking. This would tend to make me think there is a small leak in the exhaust somewhere. The sound seems to come from the top of the power head like a bearing...

    Idle speed screw on 1996 Mariner 115...where is it?

    Gents, <br />I'm doing the synch on the carbs and old man seloc tells me to adjust my "idle speed screw". According to the search I just did, it could be several places. I've got a 1996 Mariner 115 (inline 4). I do know where the idle stop, idle mixture, and idle timing screws...however the...

    need help with stator size

    does anyone know if the 18-5780 stator is the 9 amp or 16 amp variety (listed on iboats). I'm replacing the stator on my motor (original part #398-9710A33 i think it is the 16 amp) and found that some sites say the motor should have a 9-amp (sieler marine) and some say it should have an 16 amp...

    Voltage regulator/rectifier Mariner 115HP

    Hello fellas, I've got a 1996 Mariner 115HP (OG348734) and had indications of a bad Voltage regulator/rectifier (intermittent high rpms and high voltage reading). I purchased a new VRR from a Merc parts express dealer. The SN on the box he gave me shows 883072T but the part in the box has...

    parts from boat dealer....restocking fees

    this is meant for those iboats users who are familiar with parts counters at boat dealers. I bought a voltage rectifier/regulator for my Mariner 115 and noticed that on the counter a message said all returns will be charged a 20% restocking fee. Normally I wouldn't question this but once I got...

    Mariner 115 voltage regulator/rectifier help

    I've been getting intermittent high readings on tach. The motor is a 1996 Mariner 115, WOT should be 5200...but sometimes it will read 6800 with the engine sounding no different. Also, I noticed that the voltage reading on the gauge was maxed at 18 VDC when the erroneous tach reading was...

    repair kicker motor mount holes in aluminum

    I'm not sure this has been covered, I couldn't find it with a search. I wanted to put a kicker motor mount on the back of my 18' Smoker. The previous owner had a mount (i'm guessing by the 4 bolts sticking out of the transom) but has removed the business end and left the bolts. I doubt I'll...

    Transmission cooler on manual tranny

    I've seen transmission coolers on many vehicles, all of which are automatic transmissions. I was planning on towing my 18' aluminum deep-v about 900 miles and have a manual transmission in a 1992 half ton Chevy with an new 350. According to the RPO codes I have a 3.08 rear diff ratio and a...
