    Rough idle caused by Pulse pack?

    1972 100 HP Johnson on a CV-16. I let it set (preserved) for 3 years due to various reasons. Started running it this summer. Ran perfect for a couple of outings then got a little hard to start and idled rough under 1500, ( in water or on muffs no difference). Above 1500 it was flawless. I did...

If someone will tell me how to post pics I will try to get some posted. I think for now I'm going to use a...

    Add-on trim switch

    Is there a way to add a trim switch to the throttle lever on a control box that doesn't have a trim switch? I'm getting real close to installing the retrofit trim on my 72 100 HP Johnson and I need to install a trim switch. I would prefer to put it on the throttle handle but the installation...

    Servicing T&T

    I have a T&T unit from a early 80s OMC that I'm getting ready to install. I'm going through the motor replacing brushes etc. I would like to change the hydraulic fluid. Is there any special way to drain it? Are there any filters or screens that I should check or clean? How do you check the fluid...

    CV16 Question for Dhadley

    In one of my earlier post about props you mentioned about running the old motors high. My 100 Hp johnny is mounted on my CV 16 as low as it will go, The cavitation plate is about 1/4 " below the bottom. I want to raise the motor but I will have to drill one new hole on each side to do this...

    Will it fit ? for Joe R or Dhadley

    I never got an answer to this earlier. Application data for Voltage regulator P/N 585195 says for all crossflow V4s and V6s. When I look at the plate on top of my 72 100 HP it has an "ear" that sticks out and holds the temp switch for the choke in place. The regulator doesn't have this ear and...

    Adding a voltage regulator

    Can an OMC 10 amp voltage regulator P/N 585195 be installed on my 1972 100 HP Johnson? I would feel alot better if I could keep the voltage around 14 volts. If it can be, does it take the place of the rectifier or work in conjumction with it? Any tips on how to wire it would be appreciated. I...

    Prop Question

    If I go from a 12&3/4" 21" pitch uncupped aluminum to a 13&1/4' 20" pitch single cupped stainless prop, what kind of RPM change can I expect? Will the cupped prop have a lower percent of slip than the uncupped prop? <br />TIA<br /><br />Russ In Texas

    No Forward Gear

    I lost forward gear on my 72 100 hp Johnson. I show 6VDC on the "neutral wire" when the shifter is in forward. It's looking like the shift switch in the control box is shorted. Neutral & reverse are fine. Motor goes into forward when switch is off or if neutral wire is disconnected at the motor...

    Tach acts funny

    Alas, Russ is probably chasing ghosts again. 1972 100 HP Johnson,Teleflex Tach. Everything works perfect except, when at idle I put it in forward gear the tach needle jumps up 150-200 RPM. The engine speed does not change.I have verified the RPM with a hand held tach. Back to neutral or reverse...

    WOT Rpm??

    1972 100 HP johnson. In what range should the motor be at WOT? The Plate says 4500-5500. The Local OMC guy says don't turn the motor faster than 5000 cause its old??? What range should I shoot for to keep the motor happy?<br /><br />TIA<br /><br />Russ In Texas

    Gear Ratio??

    What is the gear ration on the lower unit of a 1972 100 HP Johnson? Did they change gear ratios on the 13 spline lower units as the years progressed?<br /><br />Thanks In Advance<br /><br />Russ In Texas

    OMC Control Cable Up-Grade

    I have a 1972 100 HP Johnson that I need to replace the throttle cable on. I notice Teleflex only offers the standard grade cable for the pre 1979 OMC outboards. Due to the way I have to route this cable I would like to get the better grade. How hard is it to modify the box to use the new style...

    Still worried about too much Voltage

    Going out again this weekend with second CDI powerpack. I asked a previous question about stator and rectifier outputs and have decided mine is working as advertised. I have also researched the forum enough to decide that 16 to 18 VDC is normal on unregulated systems. I have battery CD ignition...

    Stator Output??

    What should the stator output be when you check across both yellow wires? I am getting 16VAC @ idle and 18VAC @1500 rpms. The output on the rectifier (new) is 13.5 VDC @ Idle and 14.3 VDC @ 1500 rpms. Wonder what it would be @ 4500? Stator ohms out @ 1.5 both cold and warm and open from lead to...

    CDI Powerpack dies after 45 min

    I was leery about the powerpack on my 72 100 hp Johnnie so I replaced it with the CDI pack & coil.It cured the hard starting and idle problems I was having so I felt pretty good. It kind of bugged me when I checked the timing while doing link & sync because it really bounced around alot.I...

    Teleflex Temp Gauge Reads Cold

    I hooked up a Teleflex outboard temp gauge to my 100 HP Johnson. I used the "Z" bracket method to attach it to the cylinder head. It never seems to read much above "C" even when on the muffs. Direct reading thermometer shows head temp to be about 140 and the gauge will still read<br /> "C". If...
