I have a 1962 Johnson Electric Shift Seahorse 40HP and the bottom end is friend, i can pick up a 1965 Evinrude 40HP electric shift with a blown powerhead but good bottom end for $50. <br /><br />Are these parts interchangeable and will it work ok on my motor? <br /><br />Thanks for the replies guys this is a great site i dont know what i'd do without it!
