to replace marine power part # 0170-000
by Francis from Fort Myers, Florida on December 04, 2010
The iboats part number starter 18-5603 looks considerably smaller than my original for my marine power 454. I will not install untill I here it will work. Not going to blow $221.00 on something that looks too small and maybe under powered. Their web site said it replaces the marine power part 0170-000..... at this point I really doubt it.

by Derek from Kawkawlin, Michigan on September 21, 2015
The best price I could find hands down. Part worked great for my 89 Nautique. When it said 2 day shipping it was really two day shipping.

Q:
Will this starter fit my indmar 5.7 monsoon engine?
A:
We do not have the original parts list for that motor to cross reference. We will need to know OEM number to cross reference from Indmar.


Q:
Will this fit my 1986 3.7l mercruiser?
A:
We would need a serial # to confirm fitment or find the correct parts.


Q:
Will this replace the starter on my 96 sea Ray 175 series 4.3 v6 mercruiser?
A:
This is not the right one. Best thing to do is call us with your engine serial number and we can take a look to verify part. 1-800-914-1123.


Q:
What is the long red wire for - is that a resister wire - where is it used ?
A:
It is the power lead that connects to the 12V source (battery).


Q:
I have the old starter in my hand, how do I determine if I need a new one that is clockwise or counterclockwise?
A:
Point the starter away from you oi straight up to see drive gear: If the beveled edge is on the right (slanting from right to left), it has a clockwise or CW rotation. If the beveled edge is on the left (slanting from left to right), it has a counter clockwise or CCW rotation.
