Cool Jeff, thought I'd been following your posts but maybe missed a few.....there have been several.......good report on the stringers, sounds like good bones and I think you will need them....Sounds like you are going from water up, lots of work and lots of rewards....hang in there and best of luck.............John

i was expecting someone to freak out about the drillin holes, but if it just wood and fiberglass, a little resin and tiger hair to patch them up should acually make them stronger. i had to find a way to check them other than jus taking a hammer to them, i feel i did it right. atleast i know they are not rotted LOL. thanks John

Single screw rotation, Bob at beacon and I discussed rotation of engines and according to him single screw models used counter rotation engines. He said he was not the engineer but that they worked better with a counter rotation engine. The prop pics indicating clockwise from rear of engine, IMO. which when you look at the balencer on crankshaft you would have a CCW turn. We can talk about rear of engine is how Chrysler rates them and all of that but look at harmonic balancer clockwise is the standard, at least for autos and every running vehicle I have. That said it I would agree it could be reversed by the tranny. IMO not.

You change the tranny ( pump) to match the engine not to change the rotation . it turns the way the engine turns

Was told today it was a rh rev motor

Larry, I don't want to be a stickler on this but I have to caution using automotive terms and practices when discussing a marine application. If you do, you risk confusion especially when dealing with marine suppliers. For example; if you look at the balancer and tell a marine long block supplier that you want a RH engine, you will get the wrong rotation delivered. It got pretty messy in the old days and that's why the industry moved to standardize the terms and the methods by which we arrive at certain determinations. The standard for determining engine rotation in a marine application is by facing the flywheel, and that is the only way we should be reffering to it in my opinion, even if only to prevent confusion for those tuning in on the forum. This is not just a Chrysler thing!

You really want confusion; Chris Craft in thier ultimate wisdom at one time spun the engines around and drove the shafts off the front of the engine but you'd have to take a second look to realize that. These are still around today. Try working on one of them and getting the rotation terms right, holy cow Seen more than one guy totally screw up tuning these as number one cylinder is not where you'd expect it to be unless you realized the engine is actually turned around

Owens did the same thing with the flagship engines , they did it on both engines so a reverse rotaion ended up with a normal rotation out put front . What where they thinking ?? CC did a much better job.

Maybe they thought it was "forward" thinking at the time

Called bob yesterday and they flat out said "unless someone screwed the. Boat up its a rev motor", think opposite of an auto engine" that was their qoute. Then i met a marine tech at the house. 30 seconds later he said it was rev rot. I feel better now. Deff confusing deal here

hopefully close this deal tonight or tomorrow, in sure it will take time to the motor here, but at least its a big step forward

Being a stickler is many times a good thing and you are correct regarding auto vs marine but one of our members covinced me how to look at it as far as the engine is concerned and I have not been confused about which way an engine turns since. Ch rysler calls it one way other the other, they knew it was confusing and they put orange arrows on the engines and trannies. Usually on the top of the timing cover for CW or normal engines and on the raw water pump bracket for counter rotating engines and near the output, at least on my V drives.

You want to throw confusion in I have what is called a counter rotating or reverse outboard and its screw turns CCW looking at it so it would be used on port side in a pair or is okay by itself. Apparently outboard mfgs
think it better to use a right hand turning prop as well when using one engine whiche what they refer to as standard rotation.

Another way of telling a reverse 318 is under the distributor you will find a spacer about 1/2 to 3/4 inch thick, it is not used on the standard rotation. Further to confuse matters the distributor rotor will turn the same direction on both engines, different firing order though. Chrysle cut the camshaft and distributor gear at the opposite slant to make that happen.



True enough when buying parts for the driving mechanism you must know for our inboards. I actualy have labeled my new engines under the 225 cowling on the controls bracket which. engine it is and on what side

Okay I am officially old. What in the heck do bump mean?

I was about to ask the same Larry, your not old yet, I'm 35 but bump sounds like something my 18 ur old step daughter would say to me. So yes! What is it suppose to mean??
