I have a 35 HP Johnson Seahorse. I've owned it for about a year and its due for some maintenance. I have been trying to find the appropriate impeller etc but have been having trouble determining which one I need. The model # of my outboard is 35852R. I have found a couple of websites that give year etc for different model numbers. I haven't been able to find this exact model #. I have found 35852 but it says its a 1978 evinrude. So is my Johnson Seahorse an Evinrude? Is the impeller specified for model# 35852 the one I need? I appreciate any advice.
