Drop boat in local lake and test repair.
It is highly advised to opt-in for this service, in some cases it’s mandatory, as some issues do not present themselves until boat is under load.
Industry standard it to test boat at shop only. We feel this is a disservice because if the issue is not addressed or other issues arise it’s an inconvenience and added cost to have the boat pulled again and serviced. Does not apply to routine maintenance, only major repairs/engine work.
