A electric start is sweet, also you can wire into main battery bank and get some charge, also shifting forward reverse is easily done using shift cable off the A Bomb, you can buy adjustable motor brackets via many sites and save $$$$ west marines crazy price, they go by HP so get one sized right, also when we did this up grade due to age of our A bomb we beefed up transom inside boat with marine grade starboard and fiberglass to spread load prior to mounting bracket, make sure to cut out shell shield before you glass in , FYI a older 5 hp pushed our Cat 27 close to hull speed on calm days, we use our mount as back up and hang our dink engine so its a multi task system, thou a long shaft is ideal for what your doing. Good luck.
