Just a quick word of thanks for all of the advice while rebuilding my motor. We are finally in the later stages of break in. It is running great. Thanks again for the help.

I bought this boat and have rebuilt the motor. Just in the breakin phase. The boat is leaking somewhere. I think it is up front somewhere. Any ideas here? Is there any history of Cajuns leaking?
Thanks in advance,
David
Finally we are in the break in stage after doing a complete rebuild. Thank for all of the info to help us along.
One of the wires coming from the powerpack to the coil has a busted connector and the boot is falling apart.
Can you buy the connector and boot to fix this or do you have to replace...
We are just breaking in the freshly rebuilt 70hp Johnson. I have an infrared temp gun. Where should I take the temp reading and what temp should it get to at idle and max operation temp?
Thanks in advance.
I know it has been a while since my last post. The powerhead is completely rebuilt and ready to go back on the lower unit. So far the only question we have so far is:
The shifter rod coming up from the lower unit, we are having a hard time getting it connected. The OEM Manual does not describe...
In the manual it says to use OMC Tool 324891 to remove the jets in the carb. Is this necessary? Can you use a screwdriver? Any help is greatly appriciated.
Got the motor almost completely torn down. Trying to remove the intake manifold. The manual says to make a tool for removing the taper pin. It says "Do not any tool smaller than the taper pin bore to remove the pin"?????? This does not make any sense to me. It has to be smaller for it to fit in...
I am doing a complete powerhead rebuild on this engine. I am going to follow break in proceedures. I was thinking about using Amsoil products throughout. I am going to remove the VRO and go to premix. Thanks in advance for your comments.
I just received the used head. It is an aluminium head. It has oxidation all over. Looking past that it looks to be in good shape. My Dad has some Sodium Hydroxide (a cuastic). Can we use that to soak the aluminium head in to clean it? If so, how long?
In the process of rebuilding the powerhead. We have honed the cylinders. I have 2 cylinders with a score each that is about .001 or .002 deep. I am replacing all 3 pistons and rings. Will these scores really be a problem? Is this a good reason to go ahead and tear it down completly and bore the...
I am in the process of rebuilding the powerhead. In the mean time the "association" said I need to move the boat. Problem is the engine is all the way down with the powerhead off. How do I disconnect the Power Tilt and Trim so I can lift the engine?
I have a '87 Johnson 70 HP VRO. I am rebuilding it and wondering whether or not to remove the VRO and just premix. If I remove the VRO, how do I do it? What extra parts are there? If I keep the VRO, is there an alarm to tell me if the injectors are not working?
I went to the NAPA Machine Shop today to check on pricing for boring the block. The machinist asked if all pistons needed to be replaced? I told him one maybe 2. He said if I was replacing the pistons with OMC pistons I could replace just the bad ones. He said if I was planning on using...
I bought a boat with a '87 Johnson 70hp. The previous owner had to have the motor reserialized by the Texas PWD. That beins said the model number is also missing. How do you tell the difference between a J70ELCUR and a J70TLCUR? I am in the process of rebuilding this motor so the model number...
I just bought a Cajun Demon with a Johnson 70 on it. Within the first half hour I lost all power. When I got it home I did a compression test. The bottom cyclinder had 0 compression. I pulled the head and the piston was 1/4 gone, burned. My Dad and I will rebuild it. We weere wondering what...
