Smaller than the original, but works well.
When I received it, it was so small that I thought it was a toy, or maybe for some 4cyl engine. It is significantly smaller than the original one. When I looked closer, the mount holes did line up, so I tried it. I did have to get shorter mount bolts. To my surprise, it works great! I don't know what the longevity will be, but it made it through a busy august! Considering the price and how small it is, I might just buy a second one to keep on board. Just in case.

Warning!!!
I was so impressed after install!! Fired right up faster that it ever has in the past, had the boat out about 8 times and CACK!!! They say they will stand behind the product and replace it, but do I risk another day ruined on the river? Btw, I have a Volvo penta 5.0 21.5' Larson I/O

Perfect fit and functioning. Excellent support
The starter fit perfectly, in my Mercruiser 4.3 from 2004, although it was awkward to replace on my engine due to space constraints. I had a few questions for the supplier and quickly received very descriptive answers. Now the starter works perfect in my boat. In all a very good choice which I really can recommend others.

New starter
Part came promptly and was a direct match to the original starter. I did a bench test prior to install and had no issues.
