    And here we have---

    For those of you who read my last post on using the wrong plugs, I was looking for some parts down in the garage and came across this: Here we have a classic example of detonation damage due to a lean running cylinder. Note how much more severe it is than the simple melting of a hole from using...

    Effects of using bent electrode plugs.

    These photos show the neat hole melted in the piston crown at the sparkplug. Note that there is no other damage to the piston other than a bit of melting in the general area of the hole. All four pistons were damaged like this yet the engine did not have any other problems. Timing was correct...

    New reeds in old block

    Because it has been bothering me for some time as to whether or not the new square reeds are more responsive, I decided to transplant new style square reeds into my trusty old Chrysler 140 and see if they made any difference. Since the old reed blocks are five petal and the new reed blocks are...

    Michigan prop for 1987 Evinrude 50

    Anyone know what pitch a Michigan PJ 61 prop is? It is on a 50 HP 1987 Evinrude mounted on a 16 foot tin fishing boat and I think it is too much pitch. Friends boat and tachometer is broken, of course, but the boat has a lot of trouble getting up on plane. I want him to drop down two pitches but...

    Chrysler 55 converted to Force electronic.

    Tater: I'm answering this on the forum because some others may have valuable input. To summarize: You converted a Chrysler 55 HP engine with points ignition to Force 50 HP electronic ignition. You are now having trouble setting timing to 30 degrees. You are in uncharted territory since I...

    Thinking outside the box!

    A glimpse into the inner workings of the mind of Frank Acampora. Last season I was in Cabelas and found this brand new Ballistic 13 X 21 for 200 dollars. It had 15 splines and the hub diameter looked correct so I said "what the hell" and bought it. NOW I needed to make it fit my 1979 Chrysler...

    Disassembling a dual exhaust lower unit.

    I just made an interesting and useful discovery for disassembling any lower unit with a two piece drive shaft: You can put an old Evinrude 13 spline hub on the stub shaft. You can then put a pipe wrench on the hub and break free the pinion nut. Works great and you don't **** up the splines on...

    Ballistic stainless test

    I have just returned from the river and testing my new Ballistic prop. Overall, I was satisfied with the results. The test was run on a 15 foot Glastron V153 rated for 90 HP and carrying an old Chrysler 105 (actually 90). The engine has a 2 to 1 lower unit and the correct prop for this...

    Ballistic Stainless

    Last year I bought a 13 X 21 Ballistic Stainless prop. I have niot yet had a chance to try it. Before I do, I'd like to know what to generally expect. It is for my Chrysler 140 and the engine is capable of turning it within operating range so that is not my question. My question is: Is this...

    DF30 Suzuki Four cycle

    Don't kill me, I'm just the messenger. Friend finds it impossible to learn how to post on iboats! Question: What is the valve lash setting for both intake and exhaust valves on a 2005 DF 30 four cycle 30 HP? By valve lash I mean the clearance between the rocker arms and valve stems when the...

    Oh, I am SO good!

    I bought a 1997 Force 50 horsepower engine. It was described as locked up. The lower unit was covered with barnacles and it looked like a generally neglected engine. I bought it for junk with the hopes of salvaging some parts. Lo and behold: I got it home and started checking--- Tilt and...

    Barnacle Bill the Sailor!

    I just bought a salt water engine that was left down in the water for extended periods. The prop and lower unit are encrusted with old dried Barnacles anywhere from 1/4 to 3/4 inch in size. I have been scraping and while the tops come off, the bottoms of the shells seem to be much more difficult...

    For Karla and others who need to know

    This post is for those people who have no idea what is inside their Force engine. I have posted a couple of photos that I happen to have on hand. I invite others to post more photos to add to the collection. The first photo is a three cylinder Force engine, veiwing from the open bypass side...

    1960s versus later pistons

    I have been asked a couple of times if new pistons will fit in older Chrysler engines. The answer is YES--but with conditions. Look at the first photo. It shows a newer type piston flanked on either side by an older style with needle bearings in the piston itself. The wrist pin on these old...

    old bronze props.

    Anyone have a site where I could cross reference old Michigan bronze props? I have a PR 158 and I can't find info on it at the Michigan home site. I want to know the pitch. Thanks.

    Porting an old Chrysler 55

    This is in answer to a question I had received. I previously ported my old 1967 two cylinder Chrysler 55. It gave decent results, but you can't expect miracles from 44.5 cubic inches. After porting, it did drive my 15 foot Glastron V153 deep vee at 27 MPH, which I think is good for an...

    Various aftermarke props for Chrysler/Force

    I'm posting this here because it is specific for Chrysler/Force one piece lower units and some might not check the props forum. With a little imagination and a bit of work, many different aftermarket props will fit the one piece lower unit for 1979 Chrysler to 1994 Force engines. The first...

    Vortex prop re-hub

    Has anyone ever tried using a press in rubber hub on a Vortex? See, I have this brand new Vortex that's missing the bronze insert. I also have a brand new rubber hub. Being the cheap Ba---rd I am, I figured, why buy the bronze insert when I can press in a hub---------- If no one has tried...

    Difficulty in online diagnosing engine problems

    This post is directed at those people who seem to have a most difficult problem, or one that seems to be puzzling. It may explain why we sometimes can not exactly determine quickly what is happening. A fellow called me several times about a poor running engine. He cleaned the carb and...
