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.

Bit Longer than Genuine Quicksilver Starter Not same fit
It’s close to the Quicksilver Mercruiser starter but it’s not the same length and size. Also the internal gear sits differently. My 2012 Tahoe Mercruiser Alpha 3.0 has a back bracket that would not fit on because this starter is longer. I didn’t take the risk of testing it out by starting it as I noticed the gear inside sits a bit different and there is a knob on the front of the housing as the original does not. I’m not taking any chances. I just returned it and ordered the actual Quicksilver Starter that’s a little more $$ but totally worth it to have a proper fit.
