I am replacing my transom shield because it is too corroded. Can someone please tell me where to find my exact model so I can order all the seals and stuff. I’m attaching pictures. My outdrive is DP-SM 1.95
3868913 is your product model number for the stern drive itself.
4202124559 is the serial number for the drive itself.
DP-SM 1.95 is basically the drive model and gear ratio.
On the inside of the boat's transom housing assembly (further behind, 'not on the engine) there should be a similar type tag that has these same basic numbers on it....That will help narrow down what you have and some of your questions.
Once you get the number/s you should be able to input them in the following link below to see if it helps you with what you're looking for.
