My early 73 Express cruiser has two Q motors and when facing forward (looking at bow) the stbd side engine firing order is 1 5 6 3 4 2 7 8 and my port engine firing order is 1 8 7 2 4 3 6 5. When starting, the stbd engine turns clock wise and the port engine turns counter clockwise. This seams to be the opposite of what the book says. Are my engines in the wrong positions? They appear to have been rebuilt. Both starters face inboard towards centerline, and oil dipsticks are on outer sides facing the water (gunnel). I am trying to get the correct starter, and really confused. 

thank you for any help

Check out page 5 and 27 

307Q, 327Q, 350Q Engine Manual. 

The starters should be on the port side of each motor. the number one cylinder is the forward cylinder on the port side of each motor. The Chris Craft firing order is not the same as a Chevy firing order. Both distributors turn in the same direction. The port side motor is the reverse rotation motor. the dipsticks can be on either side of the motors, but both should be on the keel side of each to make oil checking easier. 

Sounds like firing order is correct for both engines. Here’s my question, if both are Q motors, and are installed correctly? If so, how can the starter motors both face inboard? 

Dan, thank you.  I will double check to see if both are on the port side of the motor. I know for certain the Stbd motor has the starter on the left side of the motor.  That is the one I have to replace and I am not sure which starter to get.

Have the starter rewound it should be cheaper and possibly quicker than buying new, also no question about fit.

The starter you need is for a left hand (standard rotation) motor. The 350q uses the mounting pad on the cylinder block. Arco electric has the exact replacement starter. The Arco part numbers are 50141 & 50142 for both starters costing around $360.

Cost is for each starter!

Sorry for bad info, it seems I don't know left from right. According to the drawings for the firing order the starboard motor is right hand rotation.

Tim mentioned that having the starter rewound/rebuilt might be cheaper, quicker, and would also reduce/eliminate the possibility of buying the wrong starter. I believe a separate forum thread exists on this topic with the same general advice---advice that I followed this summer when having the port starter rebuilt on my 69 Commander 27 (with 307Qs). The tech shop that operates out of my marina made the same recommendation and sent me the information for the starter/alternator shop where they outsource this work. It ended up costing me $100 to have it rebuilt at the recommended starter/alternator shop (Ballard Electric for me here in Seattle). My port starter is the original Prestolite starter, so has likely been rebuilt a few times over the years. As for location, my 307Q starters are on the port side of both the port and starboard engines (making removal of the starter on the port engine trickier).
