Information on fuel ratios for chrysler boat motor model 454HG serial no 3197?

Question

Hi ....we have jus bought a boat and due to never owning one would like to know if anyone could tell me the fuel ratios for a chrysler boat motor model: 454HG serial no: 3197.....and or any information about the motor.....r they reliable to run....how efficient are they when maintained properly....how often should they be serviced and do you need to pre-checks ....if so wat???.....yes im a lady taking on a pretty big challenge and would appriciate all and any answers ....thx .....

Answer 1

Chrysler hasn"t produced a outboard for quite some time so I would guess that your motor was a 45 hp produced in the 70's or possibly in the 80's. 50/1 should be the proper ratio. be sure to use a 2 stroke oil with a TCW rating. you didn't let on when the last time the engine was run. but be on the safe side throw a set of new sparkplugs and fuel filter on it.wouldn't hurt to change the lube in the lower unit too..when replacing lube in the the lower unit look at the condition of the prop. check for nicks or cracks and bent blades. as these will greatly effect the performance of the motor. check the skeg (lower portion of motor below the prop) for bends or chunks missing. check seal around prop shaft for oil leaks.

Answer 2

join the Yahoo group "Chryslercrew" for all the information you will ever need. It is run by former Chrysler Boat Corporation engineers and service people. They will also provide parts and repair documentation, answer questions, and give advice specific to Chrysler outboards. I have three Chrysler motors, and this group has made all the difference to keeping them in the water. Just search Chryslercrew to find them.

Hi there how are you? After reading your question I thought I would answer as well. I agree with everyone so far that has answered you. But one thing was not mentioned, while changing the lower unit lube also pay close attention to what the lube looks like. If its clear to black in color then your good as far as seal wise. Change anyway just to be sure due to you not saying if the motor has sat up for awhile or not. IF the lube is milky in color this indicates bad seals and that water has gotten in the lower unit. Again you never mentioned if the motor has sat up or not. If it has and the lube is milky then you will have to have the lower unit rebuilt if parts are still available. Again Chrysler has not made outboards in along time. Fuel ratio the normal is 50:1. Its ok to run a little rich on the oil but not alot. If you do then you take the chance on continually fouling the spark plugs which can get agrevating after awhile. Have the motor serviced once a year just before using it for the summer. Any marine engine when properly maintained will run efficient. Here is the bad part. This being my opinion...Chrysler back in the day just under Johnson/Evinrude made one of the worst outboards ever made. This is also made by people who had them. Chrysler went on to produce the "Force" line of outboards for which were an inprovement over the Chrysler brand but did not have success with them until Mercury bought them out. The "Force" brand of outboards that is. I hope this helps as well as what all the others have said.

thanks

Answer 4

The Fuel ratio would be 50:1 You can uae any tcw 3 rated outboard oil.If this motor is maintained properly it is one of the most reliable motors out there.It is not the fastest motor,but it is a simple reliable design.If it has been sitting there are several things you should check.First of all check tthe gear lube in the lower gearcase,if it is milky or a dark brown or black it needs changed.If it is milky or has water in it you will need to have it pressure tested & probably have some seals replaced.Also the water pump should be checked it should be replaced every 2-3 years regardless how little it is used.Next would be the fuel system gone over the fuel pump should have  the diaphragms replaced.The carburetors should be gone over & cleaned or rebuilt,this is very important for if it would run lean it will burn a piston very quickly.new spark plugs would be a good idea as well.Certain parts are getting hard to find,but most of the important things are still availible from Mercury or aftermerket.It would be best if you have an experienced outboard mechanic check it over.

Answer 5

chrysler hasnt made motors for a long time a good idea depending on how long the boat has set without being ran would be to take the motor to a mechanic that works on chrysler and have them go through the entier motor check the compression of each cylinder, change spark plugs, change lower unit gear oil, and possibly clean out the carbs as it can get gummed up if left sitting for long periods of time.   As for the fuel mixture ratios 50-1 is the norm but sometimes in older motors it can be a good idea to run a 25-1 ratio to help lubricate the engine better.   As far as chrysler being a good reliable motor to run back in the days when they made them they had a pretty solid reputation as for now they are just like any older engine if you maintain it well it should be fairly reliable as for efficincy once again older motors get less efficient with time.   The biggest problem you are going to have with a chrysler motor IS FINDING PARTS! they are still out there but harder to find as they have not been made for quite some time and if you do find them they will be more exspensive.  As far as service goes it is probably a good idea to take the boat in for a tune up every 1 to 2 years this usually cost about 100 dollars.

Hope this helps you and good luck with your new boat.
