    Anybody got a diagram of how the cooling system FLOWS for a 1987 EV 90HP ???

    I can't figure out how/where the water gets to the block/head and then how it flows to the other head. I would guess the water exits thru the exhaust housing.

    One side (STARBOARD) overheats on 1987 Ev 90 HP

    This is a project I've been working on for too long. This boat is sitting in my fathers driveway. I have never put this MOTOR in the water. Two summers ago I changed water pump and therms. I also rebuilt carbs. Last winter I changed out head gaskets and DEFLECTORS. I also put on a temperature...

    Water pressure gauge "T" connection location (1987 Ev 90HP)

    Does it matter if where I connect it, i.e. as it is coming out of motor or before it hits pisser ? Also, an extra 4' feet of this hose will badly distort my readings and should be trimmed or not a big deal and should be coiled and stowed ?

    Installing temp senders on an '87 90HP

    Could I put one of these in place of a head COVER bolt, after all there is 16 bolts per head surely replacing one (if threads and size match ) : http://www.boatersland.com/far-90402.html I have the other kind but I will have to make my own bracket (a little longer) to bend.

    Faria temp senders - '87 90HP Ev

    Any ideas on how to contour the sender holding bracket so that the sender makes good contact with the head ? I believe it needs to be flush with direct contact. (Here is a picture but the mount comes flat)...

    Replacing head cover gaskets on '87 90HP EV - gasket sealer application

    Last weekend I was putting my motor back together and when I got to this part I wasn't sure so I interpretted the manual to mean to apply the sealer to entire side of the gasket going to the heads. I applied NO sealer on side of gasket going to head covers. I did coat head cover bolts with...

    Head and head cover bolts - BRASS ?

    I recently pulled my heads off '87 90HP Evin. I ended up breaking 8 HEAD COVER bolts. I was considering replacing all these bolts (32). These bolts seemed to be not of great quality and rather expensive ( $2.50+ each). 1) Brass was a thought. I think I could find in bulk for .75 each or less...

    Water deflectors - installation ('87 90HP Evin)

    They don't seem to want to go in all the way. I even tried triple grease. What gives ? Anything else I should do while I got the heads off ? Should I soak the heads in parts cleaner ? I did not pull block. Did not break any HEAD bolts :Dand was left with 2 broken COVER bolts:( that I will...

    Penetrating oils - anybody ever try any of those FREEZE concoctions from Loctite or

    CRC ? Some guy even said he saw a mechanic use the CRC and Seafoam in tandem. The Loctite is advertized to get it -45 (45 below). I guess you can look at this as it works by shrinking things with cold vs expanding things with heat. Anybody use any of these or both ? Again I am looking at a...

    Taking heads off 1987 EV 90HP. Is this going to be rocket science ?

    I need to tap out 6 (1 + 5) cylinder head COVER bolts that won't come out. I was also encouraged from several people here to take the heads off to check the WATER DEFLECTORS. So a couple of questions. 1) The book said something about marking the pistons position with a pencil (sharp scribe)...

    Took cylinder head COVERS off 1987 90HP. Already broke 2 bolts. Only broke 4 more.

    Got 1 out with vise grips. Sprayed the others with SEA FOAM CREEP, still no go. Did not try the the trick the old man taught me, tighten a hair and then reverse. Any other ideas ? What is that white powdery residue, kind of like baking powder ? Since I already opened a can of worms ( this all...

    Busted bolts on BOTH cylinder head covers 1987 EV 90HP

    Tried to get an easy out on there but hard to drill a deep enough hole to get screw extractor in (1/4" x 20 bolts). I was thinking to remove both cylinder head covers so as to maybe be able to catch enough of the bolt with some vice grips. But there could be a CATCH 22, if they are still...

    Wiring gauges on a smaller boat in series ?

    I am installing new gauges on 17' Whaler (Katama). The console is very open and kind of small. With the idea of trying to avoid a "ball of confusion", I was planning to wire them in SERIES. I am installing 2 Temp gauges, Tach, water pressure and an ammeter. I was going to jump the red, black and...

    Which sealant for screw holes, 4200, Boat Life Caulk or Liquid ?

    I am putting an older Whaler together and don't need any water getting into the hull. I am sure its' seen enough. Was thinking 5200 but that is too much.

    Anybody using Teleflex 3300 cables ?

    I am having problems at the "link/pin assembly" i.e. shifter connection. My cable gets hung up when that assembly moves forward. It snags on part of the cable. There is a hole in the assembly that looks like it was made to correct this wit the proper parts. Right now I have a piece of heavy...

    3300 cables - could I get a photo as they go into the engine ?

    I got them in there and they seem to work but not sure what purpose those 5" long white plastic things are there for. So I just want to see as cables come into motor and at the double CLAMP thig-a-ma-jig. thanks

    Tachometer - 1987 90HP EV -System Check? Voltage regulator kit ?

    I bought some nice Faria gauges from a surplus store and now am wondering if I'm screwed:mad:. When I go to Farias' website they happen to specifically mention my model (1977-2008 88/90HP and 112/115HP) as to needing these 2 things. Actually "The voltage regulator kit is only RECOMMENDED. I got...
